A bicyclist makes a trip that consists of three parts, each in the same direction (due north) along a straight road. During the first part, she rides for 15.2 minutes at an average speed of 9.27 m/s. During the second part, she rides for 40.7 minutes at an average speed of 3.79 m/s. Finally, during the third part, she rides for 14.1 minutes at an average speed of 12.2 m/s.

(a) How far has the bicyclist traveled during the entire trip?

(b) What is the average speed of the bicyclist for the trip?
