Answer 1

Let s = Car B's speed

Car B is 15 mph faster than A, therefore

(s - 15) = Car A's speed

Write a distance equation; dist = speed * time

2(s-15) = 1.5s

2s - 30 = 1.5s

2s - 1.5s = 30

.5s = 30

s = 60 mph is car B's speed

Confirm this find the distances, they should be equal

2 (60-15) = 90

1.5 (60) = 90
