15/125 = t/72

so, t = (72 x 15)/125 => 8.64 minutes

i.e. 8 minutes and 38 seconds

time=15 (72/125) = 8.64 minutes

We can set up a ratio:

(time) / (gallons) = (time) / (gallons)

x / 72 = 15 / 125

x = (15/125) * 72

x = 3/25 * 72

x = 216/25

x = 864/100

x = 8.64 minutes

Okay, but maybe you want that in something a human would understand with some seconds? Let's take those 0.64 minutes and convert them to seconds.

0.64 (minutes) * 60 (seconds/minute)

= 38.4 seconds

8 minutes 38.4 seconds

The time needed=72(15/125)=8.64 min.

125/15 = 8.333 (gallons per minute)

72/8.333 = 8.6 minutes

125 gallons takes 15 minutes

1 gallon takes 15/125 minutes

72 gallons takes 15x72/125 = 8.64 minutes.

Probably because some people come late to answer, copy a correct answer, give everyone else a thumb down, and give themselves a thumb up in hopes their late answer will earn them points and possibly a best answer. Looking at the pattern I think it was Pinkgreen.
