Final answer:
To find out how many runners are needed for a team, divide the total distance of the race by the distance each runner will cover. In this case, 7 runners are needed for the team.
Step-by-step explanation:
To find out how many runners are needed for a team, we need to divide the total distance of the race by the distance each runner will cover. In this case, the race covers 7/8 of a mile and each runner will cover 1/8 of a mile. Therefore, we divide 7/8 by 1/8 to find out how many runners are needed:
7/8 ÷ 1/8 = 7 × 8/1 × 1/8 = 7
So, 7 runners are needed for the team.
