Question 1034037: Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h and Car B traveled the distance in 4 h Car A traveled 22 mph faster than Car B How fast did Car A travel? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call the rate of car B, r.
Then the rate of car A is r+22.
Since d = rt, we can use this equation:
4r = 2.4(r+22)
Now solve for r...
4r = 2.4r + 52.8
1.6r = 52.8
r = 33 mph so that
r+22 = 55 mph (car A)
