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
