Question

A marathon is a race that covers about 26 miles. Cindy ran 5 miles before takin her first water break. Then she ran another 7 miles to get to her next water break. After 6 more miles, she took her last water break. About how much farther does Cindy have until she reaches the finish line?

Answer 1

Adding the miles she has already ran and then subtracting that total from the 26 miles needed to the finish line tells you that Cindy would need to run eight more miles to complete the 26 mile marathon.
