How many minutes will it take two balloons to meet if a balloon 10 meters above the ground and rising 15 meters per minute and a balloon 150 meters above the ground descending at 20 meters per minute?

The two balloons are 150-10 = 140 metres apart.
They are travelling towards each other at a speed of 15+20 = 35 metres per minute.
140 m at 35 m/minute takes 140/35 = 4 minutes.

Why Does An Air Balloon Drop To The Ground?
Depends. IF you mean BALLOON then the following is the answer If it is a small cold air balloon gravity simply pulls it down as it is denser than the surrounding air (ie. it weighs more for the space it take up then the surrounding air it displaces). If it is a hot air balloon then the hot air has expanded so as to displace the heavier cold air inside and around the balloon and now being less dense than the surrounding air it simply floats upwards defeating gravity (the reality is that the balloon only appears to rise - what actually happens is that the colder air falls around the hot air). Once the hot air cools the balloon shrinks in size displacing less cold air around it and it is now denser than the surrounding air and gravity takes over and the balloon is pulled toward the earth (commonly called "down") IF you really meant a guy named Ballon he was a German ballet dancer and probably tripped IF you mean a Balloon flask as used in Chemical procedures to catch the drippings of distillation then some one only has to knock it off the bench. IF you mean the village of Ballon it is already ground. Although the air in the balloon is the same density as the air outside, the rubber weighs it down pulling it to the ground. This doesn't happen with helium balloons because they are so much less dense than air that they can carry the plastic.
What is the formula for ground speed?
The distance traveled divided by the time it took in minutes
A hot air balloon is flying 500 feet from where your standing April is 275 feet away from you what is the distance between the hot air balloon and April?
Depends on 2 things. 1. The height of the balloon. The higher it is, the greater the distance between April and the balloon. 2. The direction of both in relation to you. Presuming the balloon is at ground level, if both are in the same direction, then the distance between them is 500 minus 275 ft. If they are in opposite directions then the distance is 500 plus 275 ft. If they are in varying directions the answer could be anything between these two results.
How long would it take a water balloon to drop 200 feet?
if you ignore air resistance, it would take about 3.5 seconds; at ttat point where it hits the ground it is traveling at 75 mph. Because of the air drag, it may take a bit longer to hit the ground.
What walks backwards every three minutes?
someone that keeps finding pennys on the ground and then relized that the person in front of him/her has a hole in his/her pocket
How do hot air balloons return to the ground?
the air cools in the balloon therefor it lowers to the ground
What is the weight of an empty balloon?
There is no weight in an empty balloon. Empty balloons will not stay on the ground long enough to have any real weight.
How do air balloons lift off from the ground?
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
Can a bow and arrow pop a hot air balloon?
Not really, only small balloons will "pop". Hot air balloons that are large enough to carry people will lose air ( & lift) when the balloon is penetrated or torn. The balloon will lose its ability to stay up in the air.AnswerIt's highly unlikely that an arrow would reach a hot air balloon unless it were very close to the ground
How is density related to the flight of a hot air balloon?
Density is related to the flight of hot air balloons because the more density the harder it is to get of the ground.
How can you determine if a balloon is filled with helium gas or hydrogen gas?
Fill two balloons. One with hydrogen gas and the other with helium gas. Allow them to float on a piece of string. Taking a lighted/burning taper/splinter. , and burst the two balloons with the burning splinter. The helium filled balloon will just 'pop' and fall to the ground. The hydrogen filled balloon will 'pop with a flash of flame' So helium ; NO Flame Hydrogen ; A FLASH of FLAME.
Where do birthday balloons go when they are released in the air?
With helium filled balloons, they rise upwards as the gas inside is of a lower density than the atmosphere around them. The balloon will continue to rise and the gas inside it will expand as the atmospheric pressure decreases with increasing altitude. Eventually, the gas inside the balloon will expand enough to burst the balloon and the balloon will fall back to the ground. When and where this happens depends on weather conditions, air temperature, the rubber used in the balloon, etc.
What gas do we fill in hot air balloon?
Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.
Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
Do hot air balloons have high density when descending?
No, A hot air "balloon" (the gondola basket, rigging, burners, envelope and crew) is heavier than air. However when the envelope is filled with heated air this bubble of hot air is less dense than the air it displaces (outside the inflated envelope) and this hot air bubble exerts a buoyant lift that contracts the weight of the "balloon" and the ensemble rises into the air. The hotter the air in the bubble the higher the "balloon" will rise until it matches the "balloons" density matches that of the air around it. Thus on descent the pilot either allows the air in the bubble to cool or releases some of the hot air such that the overall density of the "balloon" ensemble is in equilibrium with air nearer the ground. In this manner the pilot achieves a controlled, gentle descent. If the "balloon" ensamble had a high density compared the surrounding air (or the bubble/envelope were to leak) it would plummet to the ground an injure the passengers.
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
