There are two simple answers.

a) You cannot travel fast enough.  You have already consumed the entire
   two minutes required to average 60 mph over the time it takes to make
   the trip.

b) 90 mph.  You will then have travelled an average of 60 mph over the
   DISTANCE of the trip.

There probably are other measures possible as well.
