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 15.1 minutes at an average speed of 8.26m/s. During the second part, she rides for 40.2 minutes at an average speed of 4.00m/s. Finally, during the third part, she rides for 9.13 minutes at an average speed of 19.1 m/s. How far has the bicyclist traveled during the entire trip? What is the average speed of the bicyclist for the trip?
