Question:
A tap fills at the rate of 250 ml in 3 sec. Find how much time will it take to fill a tank that can hold 80 liters of water by the same tank.
Answer:
It will take 16 minutes to fill up the tank.
Given:
The tap fills at the rate of 250 ml in 3 sec.
To find:
How much time will it take to fill a tank that can hold 80 liters of water by the same tank?
Explanation:
1 liter = 1000 ml
∴ 80 liters = (80×1000) ml
= 80000 ml.
The tap fills up 250 ml in 3 seconds.
∴ The tap fills up 1 ml in (3/250) seconds
∴ The tap fills up 80000 ml in _
(3×80000/250)
= (3×320) [∵ Dividing 80000 and 250 by 250.]
= 960 seconds
= (960÷60) minutes [∵ 1 minute = 60 seconds]
= 16 minutes.
∴ The tap will take 16 minutes to fill up the tank of volume 80 liters.
