Question

The rational function y=19800/x models the time, in hours, needed to fill a swimming pool, where x is the flow rate of the hose, in gallons per hour. 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. What is the total flow rate if all three hoses are used? gal/hr

Answer 1

1100

Explanation:

Answer 2

1100 gal/hr

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 =
`400 * 2 = 800 gal/hr`

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
