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
Answer:
8 minutes 38.4 seconds
