The san paulo community swimming pool can be filled in 12 hr if water enters through a pipe alone or in 30 hr if water enters th

Nuetrik [128]

Alright, lets gets started.

If water enters through a pipe alone, swimming pool can be filled in 12 hr.

Or say, in 12 hrs, swimming pool can be filled with help of pipe.

It means in 1 hr, the part of swimming pool filled = $\frac{1}{12}$ (For pipe only)

Similarly, with hose only, , in 1 hr, the part of swimming pool filled = $\frac{1}{30}$

So, water is coming from both, pipe and hose , then in 1 hr, the part of pool filled will be = $\frac{1}{12} + \frac{1}{30}$

Suppose in x hrs, with both supplies, pipe and hose, pool is filled.

Means

$\frac{1}{12} + \frac{1}{30} = \frac{1}{x}$

making common denominator

$\frac{30}{360} + \frac{12}{360} = \frac{1}{x}$

$\frac{30 + 12}{360} = \frac{1}{x}$

$\frac{42}{360} = \frac{1}{x}$

Flipping

$\frac{360}{42} = x$

$x = \frac{60}{7}$

Means 8.57 hrs : Answer

Bamboo is one of the fastest growing plants. It can grow up to 2.9 feet per day. How fast in inches per hour can bamboo grow? Sh

GrogVix [38]

To find this answer you will have to convert feet to inches. 2.9 feet equals approximately 35 inches.

So, that would mean that bamboo grows 35 inches within 24 hours. Therefore, you would divide 35 inches by 24 hours.

35/25= 1.4 inches per hour.
