Answer:
1100 gal/hr
Step-by-step explanation:
Given : Three hoses – two with a flow rate of 400 gal/hr and one with a flow rate of 300 gal/hr – are used to fill the pool.
To Find: What is the total flow rate if all three hoses are used? gal/hr
Solution:
Out of three,Two hoses with a flow rate of 400 gal/hr each
So, flow rate of 2 hoses =
Third hose flow rate = 300 gal /hr
Now we are supposed to find the total flow rate if all three hoses are used
So, total flow rate = (300+800)gal/hr =1100 gal/hr
Hence the total flow rate if all three hoses are used is 1100 gal/hr
