Answer:
B. 7.5 hours
Step-by-step explanation:
Assuming that both hoses fill at the same rate, then by simple proportion,
To raise the pool by 1 foot of water:
1 hose ---> takes 3 hours
2 hoses ----> fills twice as fast ---> will take half the time ---> 3/2 = 1.5 hrs
Hence with 2 hoses, it will take 1.5 hours to fill 1 foot of water.
to fill 5 feet of water, we will need 1.5 hours x 5 feet = 7.5 hours
