Question

It took Joan 10 hours to walk a 30-mile trail. How long did it take her to walk 9 miles at the same speed?

Answer 1

Answer: 3 hours

Step-by-step explanation:

1. We first take how much miles she goes and the hours and divide.

30 miles/10 hours= 3 miles/ per 1 hour

2. Now we take that and set up an equation to cross multiply

9/x=3/1

In 3 hours she would have gone 9 miles
