More the number of pumps lesser is the time taken to fill the tank

Number of pumps ∝ 1/Time

n = k / t

[where k = constant]

In 1st case

5 = k / (1.5)

k = 7.5

In second case

n = k / t

= 7.5 / 0.5

= 15

∴ 15 pumps are used to fill the empty tank in half an hour

Answer:

16 pumps

Step-by-step explanation:

given that,

no.of pumps are inversely proportional to time .

by problem,

  • no.of pumps - 4. x2

time - 1 hr- 60 min. 15 min

we know that,

x1xy1 =x2xy2

x1= 4&X2=60

X2=?,y2=15

According to the problem,

4x60=x2x15

240=x2x15

240/15=X2

therefore X2=16
