A water tank has a capacity of litres.
The tank is empty and is filled at the constant rate of litres per minute.
How long will it take for the tank to be full?
Let's call the capacity of the tank C liters and the rate at which it is filled R liters per minute.
To find the time it takes for the tank to be full, we need to divide the capacity of the tank by the rate at which it is being filled:
Time = C / R
So, in this case, the time it will take for the tank to be full is:
Time = capacity / filling rate = C / R
