After 1 hour the slower car will be 30 mph x 1 hour = 30 miles ahead of the faster car.
The faster car is travelling 45 mph - 30 mph = 15 mph faster than the slower car and so will cover this 30 miles in 30 miles ÷ 15 mph = 2 hours at which point it will have caught the slower car and start to over take it.

Do reflex angles measure 180 degrees?
No. A reflex angle starts after 180 degrees and ends just before 360.
What is a fraction or a decimal that repeats.?
The answer depends on the repeating string and also on other digits after the decimal point before the repeating string starts.

From some point A a car traveling at 50mph starts toward some point B 500 miles away 2 hours later a second car at point B starts traveling at 30mph towards A when will the cars meet?
You really should attempt to solve this on your own before reading this answer, otherwise you will not learn the lesson. Read and understand each step before proceeding past that step. If car A starts travelling 50mph towards another car B 500 miles away, and the second car starts two hours later towards the first car at 30mph, and can find the meeting time with a system of simultaneous equations in two unknowns. Start by writing down what you know. If car A travels at 50, then its distance as a function of time is 50T, so XA = 50T. If car B travels at 30, but starting two hours later, its distance as a function of time is 30(T-2), so XB = 30(T-2) = 30T - 60. The two cars travel 500 miles and meet, so XA + XB = 500. Plug the values of XA and XB into XA + XB = 500. This gives 50T + 30T - 60 = 500. Solve for T. The answer is 7. The cars meet after seven hours. Cross check: In seven hours, car A goes 7 times 50, or 350 miles. In five hours, car B goes 5 times 30, or 150 miles. 150 + 350 is 500.
How many hours will a car traveling at 65 miles per hour take to catch up to a car traveling at 55 miles per hour if the slower car starts one hour before the slower car?
Distance d = speed x time With one hour head start the slower car traveled d= 55x1 = 55 miles The faster car catches up when they have traveled same distance d = 65t = 55t + 55 10t = 55 t = 5.5 hours
How does a train stop and start?
A train stops and starts by the train Handel the man who's driving that train has a Handel that he pulls so the train can go faster and slower. Like up is faster (when he pulls) and down is slower.
Why do you Defrag comps?
you don't have to but when your computer gets fraged it starts to move slower because it is trying harder to find the information. when you defrag your computer it moves the info to places were it can find it better.so you can work faster.
What happens if earth starts rotating faster what happens if earth starts rotating faster?
Nothing will happen because of the gravity
Is a rocket faster than a bullet?
It can be. A bullet is traveling at the greatest speed when t leaves the barrel, and immediately starts to slow down. A rocket starts slowly, and moves faster and faster as the engines burn. To achieve orbit, the Space Shuttle would accelerate from zero to a speed of almost 28,968 kilometers per hour (18,000 miles per hour), a speed nine times faster than the average rifle bullet.

Do molecules move at the same speed in ice?
Molecules in ice can vibrate back and forth; they won't really "move" (unless the ice starts melting). They won't vibrate at the same speed; rather, they will randomly move, some faster, some slower.
What does czardas mean?
It's a kind of dance that comes from Hungary. It starts out slow then gets faster and faster.
Why do people hear a loud rumble before the shake?
The loud rumble or roaring sound people hear before an earthquake is caused by seismic waves traveling through the Earth, reaching our ears before the ground shaking starts. These waves move faster through the ground than the shaking, creating the noise. This phenomenon is known as the P-wave arrival.
