Question

Oscar cleans his teacher's overhead transparencies. He can clean 17 transparencies in 10 minutes. At this rate, how long will it take him to clean 75 transparencies? a) 44.12 minutes b) 47.24 minutes c) 52.94 minutes d) 55.88 minutes

Answer 1

To find out how long it will take Oscar to clean 75 transparencies at a rate of 17 transparencies in 10 minutes, you can set up a proportion:

(17 transparencies / 10 minutes) = (75 transparencies / x minutes)

Now, solve for x:

x = (10 minutes * 75 transparencies) / 17 transparencies

x = (750 minutes) / 17 transparencies

x ≈ 44.12 minutes

So, it will take Oscar approximately 44.12 minutes to clean 75 transparencies. Therefore, option (a) is the correct answer.
