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 8 84 yards by 10 minutes to get 88.4

Alaina Wolfe · Answer 2

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)
