Question

All finished doing chores at 9:52 a.m. He started at 7:27 a.m.
How long was he doing chores?

Answer 1

2 hours 25 minutes.

Explanation:

Let's add up the times. I think it's helpful to break it into pieces.

So from 7:27am until 9:27am, that's 2 hours.

Then from 9:27am until 9:30am, that's 3 minutes. (It's sometimes easier to get to a nice round number on the clock!)

Then 9:30am to 9:52am, that's 22 minutes. (52-30=22).

Add them up!

2 hours + 3 minutes + 22 minutes = 2 hours 25 minutes.
