Answer:
(av + bu) miles
Explanation:
Average speed = distance/time
distance = time × average speed
distance from the starting point to the beginning of the opposite direction = a hours × v mph (mph is miles per hour) = av miles
distance from the opposite direction to the end = b hours × u mph = bu miles
distance from where he started to the end = (av + bu) miles
