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

TOTAL                   8

Continuing to fill in the table,

             SPEEDS    TIME           DISTANCE

TO DROPOFF                     65

WAY BACK       55                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.
