Answer:
Average speed =
miles per hour
Step-by-step explanation:
Formula to calculate the average speed of an object is,
Average speed = 
If I travel with the speed of x mph for t hours,
Total distance covered = Speed × Time
=
=
miles
Similarly, if I travel with the speed y mph for t hours,
Total distance covered =
miles
Total distance covered by me =
miles
Total time taken to cover this distance = 
=
hours
Therefore, expression for the average speed will be,
Average speed = 
= 
=
miles per hour
