A car travels 30 meters in 15 seconds what is its average speed?
You use the formula speed = distance/time
How do you calculate seconds when given meters per second?
You can't convert between seconds, and meters/second. If you have a problem that involves speeds, use the formula: distance = speed x time.
How far is 45 seconds in meters?
There is no general conversion between time and distance. For speed problems, use the formula distance = speed x time.
How long will it takeyou to travel 100m if you are traveling at 2meters per second?
Use the Speed-Distance-Time formula. D=S x T T=D/S S=D/T Speed: 2 meters per second Distance: 100 meters. T=100/2 T= 50 seconds.
How would you find the speed of a person who walked 10 meters in 8 seconds?
Use the definition of 'speed': (distance traveled) divided by (time to travel the distance).Speed = (10/8) = (5/4) = 1.25 meters per second.If you want to massage it further . . .1.25 m/s = 4.5 km per hr = about 2.796 mph (rounded) = about 7,516 furlongs per fortnight (rounded)
How fast will you tavel if you are running 40 meters in 3 seconds?
Use the formula: Speed = distance / time. If you divide meters / seconds, the speed will obviously be in meters/second.

How do you calculate seconds when given meters per second?
You can't convert between seconds, and meters/second. If you have a problem that involves speeds, use the formula: distance = speed x time.
How far is 45 seconds in meters?
There is no general conversion between time and distance. For speed problems, use the formula distance = speed x time.
If you cycled 100 meters in 9 seconds What is the average speed?
You are supposed to use the definition of "average speed", and simply divide distance by time. The answer will be in meters/second. If you want to convert that to kilometers/hour, multiply the result by 3.6.
What is an example problem of speed and velocity?
One example problem of speed and velocity would be 'What is the speed of a sailboat traveling 100 meters in 180 seconds?' You can use a calculator to solve these types of problems.
How do you find constant speed?
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
What is the speed of a jet plane that travels 630 meters in 5 seconds?
Use the formula that defines speed:speed = distance / time
How do you solve 2.2 meters equals how many mph?
You can't convert that. One is a distance measurement, the other is a speed measurement. If it is a speed problem, use the formula distance = speed x time. In this case, you need to know how long it takes to advance those 2.2 meters. You also need to convert all the units to compatible units first - for example, using meters for distance, seconds for time, and meters/second for speed.
Ignoring the effects of air resistance what is the speed in of the object after falling 3 seconds?
Assuming (1) the object starts from rest, (2) air resistance is insignificant, the object speeds up by about 9.8 meters/second every second. That's the strength of the gravitational field. Just multiply this acceleration (9.8 meters/second2) by the time.
How far will sound travel through air in 5 seconds?
That will depend on the speed of sound - which depends mainly on what material the sound travels through. For example, the speed of sound in air is about 350 meters/second.In any case, if you divide the distance (in meters) by the speed of sound (in meters/second) you will get the time (in seconds).
What is the acceleration for a 1000 kg rocket launched that accelerates for 17 seconds then stops accelerating and ends up 4700 meters in the air at 21 seconds?
-- The rocket's initial speed was zero.-- In 21 seconds, it traveled 4,700 meters.-- Its average speed was 4,700/21 meters per second.-- Since that was its average speed, and its initial speed was zero, its final speedmust have been double that = 9,400/21 meters per second.-- Acceleration = (change in speed) / (time for the change)= (9,400/21) divided by (21) = 21.315 meters per second2 .==================================Or you could just use the formula [ D = 1/2 A T2 ] .4,700 = 1/2 A (21)29,400 = A (21)2A = 9,400 / 212 = 21.315 meters per second2Notice that we don't care wherther ther mass of the rocket is 1 milligram,1,000 kg, or a bazillion metric tons. Makes no difference.
