1. The problem statement, all variables and given/known data So I have this homework exercise which I just can't seem to solve. It sound like this: "Half his time the cyclist was driving at the speed of 20km/h, half of the LEFTOVER way he drove at the speed of 16km/h. When his bike broke he finished his journey on foot at the speed of 4km/h. What was the average speed of the cyclist?" And I already know that the answer has to 13,2km/h but I just have 0 idea how to get this. Could someone show me how to do this? Thank You in advance!
