Question

As part of the training for the cross-country team, you must run a total of 20 miles per week. You ran 5.6 miles in the first two days of the week. If you run the same amount each day for the remaining five days, how many miles must you run per day to complete the 20 miles?

Write and solve an equation to determine the number of miles, m, you must run per day.
5m + 2(5.6) = 20; m = 1.76
5m + 5.6 = 20; m = 2.88
5m − 5.6 = 20; m = 5.12
m + 5(5.6) = 20; m = 8

Answer 1

The first answer is correct

Explanation:

You have already run 11.2 miles (5.6 + 5.6). 20 - 11.2 = 8.8. You need to run 8.8 divided by 5. Each day for the next 5 days (1.76) to achieve this.
