A word problem...

As a service to all those math teachers out there who have run out of ideas for nasty word problems, I present this reality based puzzle...

A bicyclist rode 16.11 miles, pedaling 8.055 miles west and then returning 8.055 miles east. He finished the total distance in 56 minutes and 16 seconds. The first 8.055 miles riding against the wind, he averaged 14.6mph.

a) How much time in minutes did it take for this rider to complete his first 8.055 miles west?
b) What was his average speed for the 8.055 miles he rode east?
c) At the end of this ride, what was his cumulative average speed?

My apologies to any math students who have to solve this problem.
