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
