Question

You need to fill a pool that has the following dimensions.
Lenth:50 meters
Width:25 meters
Height:2 meters
The pump can output 4000 liters per second.
HOW LONG WILL IT TAKE TO FILL TH POOL?

Answer 1

Answer:

v=lwh,

50×25×2=4000

2500=4000

4000/2500=4

Answer 2

Answer:-

Given,

l = 50m

b = 25m

h = 2m

Volume of Swimming pool = lbh

= 50 * 25 * 2

= 50 * 50

= 2500 m³

Now 1 l = 1 / 1000 m³

2500 m³ = 1 / 1000 / 2500

2500 m³ = 2500000 l

Let the time taken be denoted by t

It is given that pump can output 4000l in a second,

Hence, t = 2500000/4000

t = 625 seconds

t = 10.416 minutes
