Two pumps are filling a pool. One of them is high power and can fill the pool alone in 2 hours less time than the other can do s
slega [8]

Answer:

4 hours

Step-by-step explanation:

Let x minutes be the time needed for the powerful pomp to fill the pool. Then x+120 minutes is the time needed to the other pomp to fill the pool. The powerful pomp fills \dfrac{1}{x} of the pool in a minute and the other pomp fills \dfrac{1}{x+120} of the pool in a minute. Filling together, they fill \dfrac{1}{x}+\dfrac{1}{x+120} of the pool in a minute and

144\cdot \left(\dfrac{1}{x}+\dfrac{1}{x+120}\right)

in 144 minutes.

Thus,

144\cdot \left(\dfrac{1}{x}+\dfrac{1}{x+120}\right)=1.

Solve this equation:

\dfrac{144(x+120)+144x}{x(x+120)}=1,\\ \\144x+144\cdot 120+144x=x^2+120x,\\ \\x^2-168x-17280=0,\\ \\D=(-168)^2-4\cdot (-17280)=97344,\\ \\x_{1,2}=\dfrac{-(-168)\pm \sqrt{97344}}{2}=\dfrac{168\pm 312}{2}=-72,\ 240.

Hence, it is needed the powerful pomp 240 minutes = 4 hours to fill the pool.

the book that Rudy chose to read for his book report 198 Pages you can read 9 pages in 15 minutes but he takes five minute break
konstantin123 [22]

Answer:

2:25 PM

Step-by-step explanation:

The computation of the finish time is given below:

As in the given situation Rudy could read 9 pages in 15 minutes

So in one minute she could read

= 9 ÷ 15 minutes

= 0.6 pages

Now for 198 pages she could take

= 198 × 1minute ÷ 0.6 pages

= 330 minutes

On break

= 330 ÷ 30 × 5 minutes

= 55 minutes  

Consumed minutes

= 330 + 55

= 385 min

= 6 hours and 25 min  

Now the finished time is

= 8:00 AM + 6:25

= 14:25

= 2:25 PM
