Answer:

  • a) 1.5 gal/min
  • b) 20 min

Step-by-step explanation:

Volume of the pool = 30 gallons

It took 5 min to fill 1/4 of the pool

Filling rate:

  • 5x = 1/4*30
  • x = 30/(5*4)
  • x = 30/20
  • x = 1.5 gal/min

Filling rate is 1.5 gal/min

Time needed to fill the pool:

  • 30 / 1.5 = 20 min
