C70 minutes

D75 minutes
75 minutes
E125 minutes
To find the total time it will take Keisha to complete the worksheet, we first need to find the time it takes her to complete one problem. We can do this by dividing the total time she has worked by the number of problems she has completed.
25 minutes / 20 problems = 1.25 minutes per problem
Now, we can use this rate to find the total time for her to complete the entire worksheet.
1.25 minutes per problem x 50 problems = 62.5 minutes
Therefore, the total time for Keisha to complete the worksheet is 62.5 minutes.
The correct answer is B. 62.5 minutes.
