Answer:
Speed of water flowing= 3km/hr
Into the sea
Given,
Depth(height) =2m Width(breadth) =45m
So we have to find the length,
For that, we've to convert km into meter and hour into min...
L
we know that,1km=1000m
then,3km=3000m
and, 1 hr =60min
So, length=3000/60
= 50m/min
Therefore, volm of water= 50x45x2
that runs into the sea per min
=4500m^3
