To find the average speed on the return journey, we first need to calculate the total distance traveled and the total time taken for the return journey.

The driver traveled 10 miles from Bechem back to Sunyani. So, the total distance for the return journey is 10 miles.

The total time taken for the return journey is 120 minutes.

Therefore, the average speed on the return journey is:

Average speed = total distance / total time
Average speed = 10 miles / 120 minutes = 0.083 miles per minute

Therefore, the average speed on the return journey is 0.083 miles per minute.
