Two cars leave from the same place at the same time. One is traveling at 60 MPH and the other at 65 MPH. The latter arrives 1 hour before the other. How many miles did they drive?
This isn't a riddle but a math problem so here is how to do it...
Distance = Speed x Time
The car traveling faster will arrive first and both cars traveled the same distance.
60 (x +1) = distance
65x = distance
Solve for x then solve for distance.
60(x+1) = 65x
The faster car travels for 12 hours and covers 780 miles , the slower car will have travelled 720 miles in the same time and will have one hours more driving to arrive.
