Question

Ava and Kelly ran a road race, starting from the same place at the same time. Ava ran at an average speed of 6 miles per hour. Kelly ran at an average speed of 8 miles per hour. b If Kelly finished the race in 1 1/2 hours, how long did it take Ava to finish the race?

Answer 1

Answer:

2

Step-by-step explanation:

Kelly ran at an average speed of 8 miles per hour. If she finished the race in one and a half hours that means she ran 12 miles.

8=x

?=3/2x

12=x

We now know the road is 12 miles long. Ava has an average speed of 6 miles so she will finish it in 12/6 hours.

12/6=2
