Question

Robert is preparing to run a marathon. He runs 7 1/5 miles on Saturday and two times that amount on Monday and Wednesday. Robert wants to run a total of 60 miles this week. How many more miles does he need to run?

Answer 1

25 miles

Explanation:

Robert runs 7 1/5 miles on Saturday. To find out how much he runs on Monday and Wednesday, we can multiply 7 1/5 by 2:

7 1/5 x 2 = 14 2/5

Robert runs 14 2/5 miles on both Monday and Wednesday, so his total distance for the week is:

7 1/5 + 14 2/5 + 14 2/5 = 35 miles

Robert wants to run a total of 60 miles this week, so he needs to run:

60 - 35 = 25 miles

Therefore, Robert needs to run 25 more miles to reach his goal of running 60 miles this week.
