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?

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
