Question

9:00 am to 6:40 pm what are the minutes between them​

Answer 1

580 minutes (if you are asking how many minutes in between the two times)

Explanation:

9 to 6 is 9 hours.

1 hours is 60 minutes so 9hours is 60*9 which is 540.

Then there is the 40 minutes from 6:40.

540 min + 40 min = 580 minutes
