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 27.8 minutes at an average speed of 5.70 m/s. During the second part, she rides for 25.6 minutes at an average speed of 4.07 m/s. Finally, during the third part, she rides for 6.24 minutes at an average speed of 15.3 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?
