I drove to my parents' house at 40 miles per hour. If I had driven 30 miles an hour instead, then I would have gotten there 20 minutes later. How many miles did I drive?

rate  *  time = distance

distance is same  so equate:

40 m/hr  *  x    =    30 m/hr (x+1/3)     solve for x =   1 hour      (be careful....you need to change 20 min into 1/3 hour becuase the other parameters are in miles/hr)                          

    40 m/hr x 1 hr = 40 miles
