Amy had to solve 26 problems. After 3.6 hours, she had 8 problems left to solve. If she solved the same number of problems each hour, how many more hours does she need to work in order to complete the remaining problems?

26-8 = 18

She answered 18 questions in 3.6 hours.

18 problems/ 3.6 hours = 5 problems per hour.

8 problems / 5 problems per hour = 1.6 hours more are needed.
