Answer:
3 months
Explanation:
in order to find how many months it would take for Alex to drive 6,750 miles we have to find how many miles he drives in a month so you would have to divide 20,250 by 9:
20,250/9 = 2,250 miles per month
you then divide 6,750 by 2,250 to get the number it months it would take him to drive 6,750 miles:
6,750/2,250= 3
It would take him 3 months to drive 6,750 miles
