A bicyclist rides the first 60 km of a 220 km race in 1.5 hours. What is the bicyclist average speed? I know that the answer is 7.5, however I'm trying to establish a formula for solving problems such as this one. Is there a formula that you can provide to solve problems that require calculating miles per hour based on only feet and seconds?
