Question

It takes Fred 9 minutes to type and spell check 13 pages of a manuscript. Find how long it takes him to type and spell check 60 pages. Round to the nearest whole number.

Answer: _______ minutes

Just put numerical answer.

Answer 1

Fred’s ratio of minutes to pages is 9:13.

9/13=x/60

Cross-multiply. 9*60=13x, so 540=13x and 540/13=x.

Rounding up to the nearest whole number, the answer is 42 minutes.
