two cars leave from Albany, New York.....

Question

Two cars leave from Albany, New York, at the same time and travel directly north. One car travels one and one-half times as fast as the other. After 4 hours and 45 minutes, they are 95 miles apart. What is the speed of each car?

Answer 1

 

What you do is take the 95 mile difference between the two cars and divide that by 4.75 (the total time driven).

 

95/4.75= 20

 

So, the faster car is travelling 20 miles per hour faster than the slower car.

 

It does not matter if the fast car is going 40mph, 50mph, or whatever; as long as its travelling 20mph faster than the other car, it will be 95 miles further down the road after 4 hours and 45 minutes.
