If you planned to bike to a park that was five miles away, what average speed would you have to maintain to arrive in about 15 m
AfilCa [17]

The average speed you need to maintain is 0.33 miles per minute.

The average speed is the speed that you maintain throughout the journey. It is obtained as; Total distance covered/Total time taken

If we have the following information from the question;

Distance covered = 5 miles

Time taken = 15 mins

Then it follows that;

Average speed = Distance/time

Average speed= 5 miles/15mins

Average speed = 0.33 miles per minute.
