8.

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

Answer 1

So first you need to multiply 25 and 3 which is 75. So it took her 75 minutes or 1 hour and 15 minutes to do it. If she finished at 4:20 she would have started at 3:05.

Hope this helps!!!

Answer 2

3:45 is the answer because i multiplied 25 (the questions she did ) and 3 (how long it took her to do the problems) i got 75 which i subtracted by 420 (the time. she ended ) which got 3:45
