Total distance for the journey from Sunyani to Kumasi and back to Sunyani = 40 miles + 40 miles = 80 miles

Total time taken for the whole journey = 60 minutes (Sunyani to Bechem) + 30 minutes (rest) + 60 minutes (Bechem to Kumasi) + 30 minutes (rest) + 120 minutes (Kumasi to Sunyani) = 300 minutes

Average speed = Total distance / Total time = 80 miles / 300 minutes = 0.2667 miles per minute

Therefore, the average speed for the whole journey is 0.2667 miles per minute.
