Question

A team of runners ran a relay race. Each runner ran 7 1/2 kilometers. The total length of the race was 45 kilometers. Write and solve an equation to find how many runners were on the team. *

Answer 1

6 runners

Explanation:

Each runner ran 7.5 km. If there were n runners, then (7.5 km)n = 45 km.

Solve this for n by dividing 7.5 km into 45 km:

n = 6

There were 6 runners.
