Work out the time it would take her to complete one problem (time taken ÷ problems done) and then multiply that answer by the total number of problems to work out the total time.

So that would be:
25 minutes ÷ 20 problems = 1.25 problems per minute
1.25 problems per minute × 50 problems total = 62.5 minutes total.

The answer is: B) 62.5 minutes.
