An inlet pipe on a swimming pool can be used to fill the pool in 40 hours. The drain pipe can be used to empty the pool in 42 ho

statuscvo [17]

Answer:

Pool will be filled in 280 hours

Step-by-step explanation:

Inlet pipe fills in 40 hours = 1 pool

Inlet pipe fills in 1 hours = $\frac{1}{40}$

Drain pipe empty in 42 hours = 1 pool

Drain pipe empty in 1 hour = $\frac{1}{42}$

If both pipes are opened together

then in pool fills in 1 hour = $\frac{1}{40}$ - $\frac{1}{42}$

on simplifying the right side ,we get $\frac{42-40}{(40)(42)}$

= $\frac{2}{(40)(42)}$

= $\frac{1}{840}$

$\frac{1}{840}$ pool fills in 1 hour

1 pool will be filled in 840 hours

$\frac{2}{3}$ pool is filled

empty pool = 1 - $\frac{2}{3}$ = $\frac{1}{3}$

therfore $\frac{1}{3}$ pool will be filled in $\frac{1}{3}$ X 840 =

= 280 hours
