Question

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the distance in 4.5 h. Car B traveled 5 mph slower than Car A.

(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)

How fast did Car B travel?

Enter your answer in the box.

Answer 1

4*Y=4.5*(Y-5)
4.5Y-4Y=22.5
0.5Y=22.5
Y=45mph

CAR B travelled @ 40mph
