It would take Regina 250 minutes to type 20 pages because we would first divide 500 words by 40 words (40 words equaling 1 minute) to first find out how long it took her to type 1 page. After finding it was 12.5 mins we then multiple, 12.5 x 20 which gives us 250 minutes. Which is also 4 hours and 10 minutes I believe.
