mph

Answer 1

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?
:
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
