**Reiny**, Friday, July 5, 2013 at 8:57pmdefine your variables:

let the rate of the the slower car be x mph

then the rate of the faster car is x+13 mph

They both drive for 4 hours

distance covered by slower car = 4x

distance covered by faster car = 4(x+13)

4x + 4(x+13) = 460

8x 408

x = 51

slower car went 51 mph

faster car went 64 mph
