discuss the effect of poaching on animals that are poached
Answers
SolutioN :-
Let the speed of the stream be x km/h.
so, speed of boat in downstream is ( 11 + x )
and also speed of boat in upstream is ( 11 - x )
Distance cover by boat is 12 km.
The speed of boat in still water is 11 km/h
\boxed{\tt \bullet \: \: \: Distance = Speed \times Time.}
∙Distance=Speed×Time.
\begin{gathered} \tt \rightarrow \dfrac{12}{11 - x} + \dfrac{12}{11 + x} = 2 \times \dfrac{3}{4} \\ \\ \end{gathered}

Explanation:
Many wildlife animals, therefore, help maintain the food chain and food web balance in the wild meaning that if they are taken away, the ecosystem is disturbed and this could lead to the death of even more animals and plant species due to explosive growth of other species.
