Question

A river $2m$ deep and $43m$ wide is flowing at the rate of $3km/hr$. Find the quantity of water that runs into the sea per minute.

Answer 1

Quantity of water in $1$ min= Cross $△le$ of river $m^2$ $\times$ Rate $\times$ (1 min in min)

$=(2\times 43)\times \left(\frac{3000}{1\times 60}\right)m^3$

$=4300m^3$
