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.
