A castle has to be guarded 24 hours a day. Five knights are ordered to split each day guard duty equally. How long will each knight spend on guard duty in one day?

Well, to start, divide the 24 hours among the 5 guards to get 4.8 hrs. If you need the answer in hours and minutes, simply multiply .8 by 60 to find how many minutes 80% of 60 is to get 48 minutes.
Each guard would have to spend 4 hours and 48 minutes on guard duty.
