Question

Bethany finished her math homework at 4:20 p.M. She did 25 multiplication problems in all. If each problem took her 3 minutes to do, at what time did Bethany start her math homework?

Answer 1

Bethany started het homework at 3.05 PM approx 3 PM.

Explanation:

The number of problems completed by Bethany = 25

The time taken to complete 1 problem = 3 minutes

The time taken to complete 25 problems = 25 * 3 = 75 minutes

Bethany finished her math homework at 4:20 p.M.

So she started 75 minutes 4.20 PM, (i.e) 3.05 PM or

approx around 3 PM.
