Average speed = (total distance covered) / (time to cover the distance)

total distance covered = (516 + 368) = 884 yards
time to cover the distance = (6 + 4) = 10 minutes

Average speed = (884 yards) / (10 minutes)  =  88.4 yds/min (C)

Hello.

The answer would be C. 88.4.

You have to add the total  distance (yards) and then divide it by the total time (minutes).

So you would divide 884 yards by 10 minutes to get 88.4

Have a ncie day
