Answer 2

Given - Rate of filling a tank

Find - Time taken to fill the half-tank

Solution - It will take 40 minutes to fill half capacity of the tank.

The half capacity of the tank will be = 400/2

The half capacity of the tank = 200 litres

Now, the tap can fill 5 litres in 1 minute.

So, it will fill 200 litres in number of minutes = 1/5*200

Number of minutes = 200/5

Number of minutes = 40 minutes

Therefore, it will take 40 minutes to fill half capacity of the tank.
