**Answer This Question**

Plz help, without using algebra, Thank u!

so in 1hr, 1/6 of the tank is full

full tank only by hose B: 3hrs

so in 1 hr, 1/3 of the tank is full.

if both are open for 1 hour:

1/6 + 1/3 = 1/2 of the tank will be full.

So 1/2 tank is full in 1 hour, hence full tank will take 2 hours when both hoses are open.
