Question

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster that car A. How fast did Car B travel?

Answer 1

Let the speed of car B be x.
Car B is faster than car A 15mph so the speed of car A would be: x-15.
From the problem, we could come up with an equation:
$2(x - 15) = 1.5x \\ x = 60$
So car B was traveling at 60mph
