amy drove her car the same distance in six hours that juan drove his car in 5 1/2 hours. find the speed (rate) of amy's car, given that she drove 5 mi/h slower than juan.

  • math -

    let Juan's speed be x mph
    then Amy's speed is (x-5) mph

    then 6(x-5) = 5.5x
    solve for x, sub it back into x-5

    (I got 55 mph for Amy)
