A tank can be filled by pipe A in 6 hours, and by pipe B in 8 hours. Pipe C can empty the full tank in 12 hours. If all three pipes are opened together, how long will it take to fill the tank?
4.8 hours, or 4 hours 48 minutes
Determine rates per hour:
Pipe A fills 1/6 of the tank per hour.
Pipe B fills 1/8 of the tank per hour.
Pipe C empties 1/12 of the tank per hour.
Combine rates:
Net rate=1/6 + 1/8 - 1/12
Find common denominator (24):
4/24 + 3/24 - 2/24 = 5/24
Time to fill the tank:
Time= 1 tank / (5/24) = 24/5 = 4.8 hours
