How many hours did Judy work on Monday,Tuesday,and Wednesday?

Question

Monday=3hours and 15minutes
Tuesday=5hours and 30minutes
Wednesday=4hours and 45minutes

I got 1hour and 30minutes in all.. Is that correct?

Answer 1

No.

Think again.

Answer 2

After I add all the numbers I get 12:90..

I don't get what I'm suppose to do next

Answer 3

Yes, it's 12 hours and 90 minutes

60 minutes = 1 hour

So it's 13 hours and 30 minutes.

Answer 4

So I was suppose to add 1 hour to 12hours and 90minutes?

Answer 5

Yes. You regroup (or borrow) 60 minutes from 90 minutes and add it to 12 hours.

Answer 6

Oh.
I get it now! Thanks

Answer 7

Yay! :-)

You're welcome.
