Assuming 24 hour times since no am/pm are present (though I would normally expect two digits for the hour, as in 08:15, etc) - 20 hours 30 mins.

If the question is from 8:15am to 4:45pm (sounds like a plausible working day) then it is 12 hours less at 8 hr 30 min.

8 15 to 4 45 is:

08:15 to 09:00= 45 mins plus

9:00 to 12:00 = 3 hours plus

12:00 to 24:00 = 12 hours plus

00:00 to 04:00 = 4 hours plus

04:00 to 04:45 = 45 mins

Which is 45 min + 3 hr + 12 hr + 4 hr + 45 min = 19 hr 90 min

But 90 min = 1 hr 30, so total is 20 hr 30 min
