An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. the drain pipe can be used to empty the pool in 34 hours. if the pool is 1/3 filled and than the inlet pipe and drain pipe are opened how long would it take to fill the pool

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs

Solution:

Let x = time it will take to fill the pool

= work rate of inlet pipe

= work rate of drain pipe

Using the formulae

Volume of flow=work rate time

Let us assume complete time of pool to fill = 1

Remaining fraction of pool to be filled =

Time it will take to fill the pool = 748 hrs

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
