Q:
It takes a hose 5 minutes to fill a rectangular aquarium 11 inches long, 13 inches wide, and 14 inches tall. how long will it take the same hose to fill an aquarium measuring 21 inches by 24 inches by 30 inches?
Accepted Solution
A:
volume of 1st aquarium = 11 * 13 * 14 = 2002
volume of 2nd aquarium = 21 * 14 * 30 = 8820
if 5 minutes = 2002
1 minute = 2002\5 = 400.4
minutes to fill the 2nd aquarium is 8820/400.4 = 22.028(approximately)
