Question

Two cars start driving in the same direction from the same place. If one travels 58

mph and the other 67

mph, how long will it take them to be 27

miles apart?

Answer 1

d = rt, right?

 

The faster car will obviously be 27 miles further in our found time.

 

58t + 27 = 67t

9t = 27

t = 3

 

3 hours
