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.

Sophie [7]
The founders of the New England colonies had an entirely different mission from the Jamestown settlers. Although economic prosperity was still a goal of the New England settlers, their true goal was spiritual. Fed up with the ceremonial Church of England, Pilgrims and Puritans sought to recreate society in the manner they believed God truly intended it to be designed.....  basically Clatholic
