Today I am going to tell you the answer for that question.
1st step: Put number 15 Litres in the litres place because we want to find out how many litres can we fill up in how many minutes.
2nd step: Put 1 minute in the minute place so we know that we can pour 15 litres in 1 minute.
| litres | Minutes |
| 15 litres | 1 Minutes |

3rd step: Since we want to find how many litres can we fill in 20 minutes we are going to put the 20 minutes in the minutes section.

| minutes |
15 litres
| 1 minute |
| 20 minutes |
4th step: Look in the minute section, from 1 minute to 20 minute we have to times 20 so all we need to do is 15 times 20 than we can find out the volume of the tank. 15 * 20 = 300
| Litres | Minutes |
| 15 litres | 1 minute |
| Answer: 300 litres | 20 minutes |
Hope you got it right!
