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?

Answer 1

Set up a proportion.

$\sf\dfrac{20}{25}=\dfrac{50}{x}$

Cross multiply:

$\sf1250=20x$

Divide 20 to both sides:

$\sf~x=62.5$

So it will take 62.5 minutes for her to complete the worksheet.

Answer 2

Answer:

It will take her 62.5 min to finish her homework
