You can put this solution on YOUR website!
RT=D relates rate, time, and distance.
Also R=D/T.

Going exactly according to the description, the distance to drop off and the distance to return back are equal, so both 65 miles. 

             SPEEDS    TIME           DISTANCE

TO DROPOFF                             65

WAY BACK       55     65%2F55           65

TOTAL                   8


Continuing to fill in the table,
             SPEEDS    TIME           DISTANCE

TO DROPOFF             8-13%2F11        65

WAY BACK       55     13%2F11           65

TOTAL                   8

You can now compute both time quantities.

-
Return trip was 1 hour 11 minutes
and
trip to make drop-off was 6 hours 41 minutes.
