Question

Marcus needs to bike at least 80 miles this week for his training. If he has already biked 25 miles this week, then how many miles should he bike on each of the 5 remaining days this week ?

Answer 1

11 miles each day

Explanation:

Marcus needs 80 miles a week. Has already ridden 25 miles.

80-25 = 55.

Marcus has 55 miles left to ride for the week and has 5 days to do it in.

Assuming he rides the same amount each day:

55 / 5 = 11 miles biked each day.

Check our work

5 days riding 11 miles a day would be 55 miles.

25 miles are already completed.

55 + 25 = 80
