Question

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?
 
 
  ______ mph

hellokitty17 · Answer

Let speed of car B be x
Speed of car A is (x - 15)

Distance traveled by car B in 1.5 h = x * 1.5
Distance traveled by car A in 2 h = (x - 15) * 2

These two distances are equal

Therefore, 1.5x = 2(x - 15)
1.5x = 2x - 30
subtract 1,5x
0 = 0.5x - 30
add 30
30 = 0.5x
divide by 0.5
30/0.5 = x
x = 60
