1x1 = 2
3x3 = 18
5x5 = 50
7 x7 = ?

30x2=60 (to find one pump) 60/5=12
It would take 12 hours so it would be quicker by 18 hours

If five **similar **pumps were used instead, the swimming pool will be filled 18 hours quicker .
Given that:
A swimming pool is filled in 30 hours by two identical pumps.
So, the **rate **at which two pumps fill the pool is 1/30.
Let x be the time taken by 1 pump to fill the tank.
Then the rate at which the pool is filled by each tank = 1/x.
So,
1/x + 1/x = 1/30
2/x = 1/30
x = 2 × 30
x = 60.
So, a pump will take 60 **hours **to fill the tank if it is filled alone.
If five pumps are used instead,
1/60 + 1/60 + 1/60 + 1/60 + 1/60 = 1/t
5/60 = 1/t
5t = 60
t = 12
So, it will take 12 hours to fill the pool by 5 pumps.
So 5 pumps will fill the tank 30 - 12 = 18 hours quicker.

Using five pumps will fill the swimming pool in 12 hours, which is 18 hours quicker than the 30 hours it takes with two pumps. Each pump fills at a rate of 1/60 pools per hour. Therefore, the increased number of pumps significantly reduces the total time to fill the pool.
