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 1

let car A travel at x mph

speed = distance/time

for car A we have

x = d / 2.4

so d = 2.4x

for car B we have

x + 22 = d / 4

so d = 4(x + 22)

distances are the same

so

4(x + 22) = 2.4x

solve this equation for x to get speed for car A.

Answer 2

oops - sorry - i made an error
speed for car B is x - 22 of course - Car A is the faster

Answer 3

so the equation is
4(x - 22) = 2.4x

Answer 4

Ok - do you follow that?

Answer 5

sorry!
