Question

It takes a hose 4 minutes to fill a rectangular aquarium 12 inches long, 13 inches wide, and 14 inches tall. How long will it take the same hose to fill an aquarium measuring 23 inches by 25 inches by 29 inches?

Answer 1

volume of aquarium1 = 12*13*14 = 2184 cubic inches

 

Volume of aquarium2 = 23*25*29 = 16675

 

ratio of volumes = ratio of time taken

 

16675/2184 = T/4

 

T = 30.5 minutes
