If break starts at 2:45pm this friday, the 26th, and we are back at 7:45am april 5, how many hours of vacation do we get? (add y
Black_prince [1.1K]

Answer: 9 days + 17 hours

Step-by-step explanation:

Lets calculate the hours first. Because the minutes are the same lets just calculate hours.

12-2=10

Now we add the morning hours.

7+10=17

Now all we have to do is add the days. We also have to keep in mind that this Friday is the 26th. It would also be 5 days until the month ends.

Because we already calculated the rest of the day of the 26th and 5th of April we won't include those as days.

5+4=9 days.

I added the five days until March ended and the 4 days of april. We aren't adding the 5th day of April since we already calculated the hours.

9 days + 17 hours
