Answer 2

distance = 80 miles

Explanation:

The rate is distance over time

rate = 15 miles/ 90 minutes

Converting the minutes to hours

90 minutes * 1 hours / 60 minutes = 1.5 hours

rate = 15 miles / 1.5 hours = 10 miles/ hour

We know distance rate * time

She rides 8 hours per week

distance = 10 miles / hour * 8 hours

distance = 80 miles
