Final answer:
To determine the number of people on the relay team, divide the total distance by the distance of each portion.
Step-by-step explanation:
To determine how many people will need to be on the relay team, we need to find how many portions of the relay are in 1 1/2 miles. Each portion is 1/4 of a mile. To find the number of portions, we can divide the total distance by the distance of each portion:
1 1/2 miles ÷ 1/4 mile = 6 portions
Therefore, there will need to be 6 people on the relay team.
