The empty gas tank of a motor boat is to be filled. The tank is shaped like a rectangular prism with length 25cm, width 24cm, and height 16cm. Suppose gas is pumped into the tank at a rate of 640cm3 per minute. How many minutes does it take to fill the empty tank?minutes

An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 33in, width 26in, and height 12in. Suppose water is pumped out of the aquarium at a rate of 396in3 per minute. If the aquarium starts completely full, how many minutes does it take to empty the aquarium?

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 4 ft long with a diameter of 2.2 ft. Suppose oil is drained at a rate of 2.3 ft3 per minute. If the tank starts completely full, how many minutes will it take to empty the tank?Use the value 3.14 for π, and round your answer to the nearest minute. Do not round any intermediate computations.

A rectangular water tank measures 2.5m long, 2.4m wide and 2.1m high. The tank contained some water up to a height of 1.21m.An inlet pipe was opened and water let to flow into the tank at a rate of 8 litres per minute. After one hour, a drain pipe was opened and water allowed to flow out of the tank at a rate of 6 litres per minute.Calculatei. The height of water in tank after 3 hours.ii. The total time taken to fill up the tank.

There are 3 taps, A, B and C, which can fill a tank in 20, 30 and 40 minutes, respectively. The tank has 2 holes, one at the bottom of the tank, and the other at half the height of the tank. The hole at the bottom of the tank can empty it in 120 minutes and the other hole also empties at the same rate. If all the taps are opened, find the time taken to fill the tank. min min min min
