Answer 1

Hi there!

1:28

1.Add extra hour into first term:

`5:28=6:28`

Now there is 1 hour..

2.Subtract the two terms in minute place:

`52-28=24`

3.Combine the terms:

`1:00+24=1:24`

Therefore, Keiko took 1:28 minute on the assignment.

Answer 2

It took her 84 minutes (or 1 hour and 24 minutes) to finish.
