Answer: You spent 31.39 minutes reading.
Explanation:
Hi, to answer this question we have to analyze the information given ( you write the numbers doubled, 9.759.75 is 9.75)
If you read 9.759.75 pages in your science book and it takes you 1.2 minutes to read each page, we simply have to multiply the numbers of pages by the time spent for each page.
9.75 pages x 1.21 minutes = 11.79 minutes
We do the same thing for the play:
24.5 pages x 0.8minutes = 19.6 minutes
Finally, we sum both results:
11.79 m + 19.6 m =31.39
You spent 31.39 minutes reading.
