Pump 'A' can fill 1/6 of the tank in one hour. 1/6 is the same as 2/12 Pump 'B' can drain 1/12 of the tank in one hour. If both pumps are running at the same time, then in one hour 2/12 get filled and 1/12 gets drained, and the net effect is 1/12 getting filled in that hour. If the tank is initially empty and both pumps start at the same time, then the tank will fill in 12 hours. *edit* It takes six hours if pump B is left off.

1 hour and a half, or 90 minutes.
If the miles are nautical ones, then it takes (3)/(the boat's speed in knots) hours. If the miles are statute ones, then it takes (2.6053)/(the boat's speed in knots) hours.

1.5 hours if the rate of flow is constant.
15000waypoint / 1600gallons/h = Time9.375 hours
It depends... how long, wide, and deep it is.
I get the feeling this is your homework ;) empty rate per minute = 1/20 bath fill rate per minute = 1/12 bath find t= minutes to when bath is full, 1/t bath (combined empty and fill rate) so 1/12 - 1/20 = 1/t solve that for t and you have your answer in minutes ;)
About 4 hours for marine diesel. Bunker fuel takes a bit longer as it needs to be heated and is hard to pump.
