The table below shows how the number of hours needed to fill a pool depends on the flow rate of the hoses used to fill it.

Flow rate, x
(gal/hr)
Time, y
(hours)
60
300
45
400
36
500
30
600

How long will it take to fill the pool if two hoses are used, one that fills at a rate of 40 gallons per hour and one that fills at a rate of 60 gallons per hour?
100 hours
150 hours
180 hours
200 hours

Sagot :

Answer:

C

Step-by-step explanation:

The number of hours to fill the pool will be 180. Then the correct option is C.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

The table below shows how the number of hours needed to fill a pool depends on the flow rate of the hoses used to fill it.

Flow rate (gal/hr)                   Time (hours)

           x                                          y

         60                                       300

         45                                       400

         36                                       500

         30                                       600

Then the amount of liquid in the pool will be

⇒ 60 x 300

⇒ 18,000 gallons

If this much liquid is filled with hose that has a rate of 40 gallons per hour, then the number of hours will be

⇒ 18,000 / 40

⇒ 450 hours

Then the number of hours if two hoses are used to fill the pool that one has a rate of 40 gallons per hour and one has a rate of 60 gallons per hour will be

1/T = 1/450 + 1/300

1/T = 1 / 180

  T = 180 hours

Then the number of hours to fill the pool will be 180.

Then the correct option is C.
