Hey dear,
● Answer-
v = 5 km/hr
● Explaination-
Let vm be velocity of man and vr be that for rain.
Man is walking horizontally and rain is falling vertically, so these two velocities are perpendicular to each other.
Resultant velocity of rain to man is-
v = √(vr^2 + vm^2)
v = √(3^2 + 4^2)
v = √(9 + 16)
v = √(25)
v = 5 km/hr
Therefore, rain will fall down on man with velocity 5 km/hr.
