Question

A tap can fill to fifth of a tank in 8 minutes
How much of the tank will be filled in 20 minutes?
How much time will it take to fill the half the tank?

Answer 1

Answer:

1. full

2. 10 mins

Step-by-step explanation:

a. Quantity of water a tap can fill of tank in 8 minutes = 2/5

Quantity of water a tap can fill of a tank in 1 minute= 2/5/8 = 2/5x1/8= 2/40= 1/20

Quantity of water a tap can fill of a tank in 20 minutes= 1/20x20= 1

So a tap can fill the full tank in 20 minutes

b. It takes 20 minutes to fill full tank

So it will take 20/2= 10 minutes to fill half of the tank
