Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A. How fast did Car B travel? (The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.) Enter your answer for the box.
Accepted Solution
A:
recall your d = rt, distance = rate * time
distance is the same "d" miles for each, if car A is going at a speed of "r", then B is going at a speed of "r+15"
