Question

Keisha is working on a math worksheet with 50 problems. She has completed 20 problems in 25 minutes. If she continues at the same pace, what will the total time be for her to complete the worksheet?

A) 31.25 minutes
B) 62.5 minutes
C) 70 minutes
D) 75 minutes

Answer 1

10 problems = 12.5 minutes

Now we add minutes, and we're looking for total time to complete the worksheet.

20 problems = 25 minutes

20+20+10 = 50.

25 min + 25 min + 12.5 min.

50 + 12.5 = 62.5

62.5 minutes in total to complete the worksheet.
