Question

An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 25 in, width 19 in, and height 12 in. Suppose water is pumped out
of the aquarium at a rate of 475 in per minute. If the aquarium starts completely full, how many minutes does it take to empty the aquarium. ( NO LINKS)

Answer 1

9514 1404 393

Answer:

  12 minutes

Step-by-step explanation:

The volume of the aquarium is ...

  V = LWH

  V = (25 in)(19 in)(12 in) = 5700 in³

The time required to empty it is given by ...

  time = quantity/rate

  time = (5700 in³)/(475 in³/min) = 12 min

It takes 12 minutes to empty the aquarium.
