How to solve: If a man walk with speed of 2km/hour and rain fall became in the shape of 90 degree.then find out velocity n direction of rain if man walk with speed of 4km/hour and angle of rain is 45 degree
90 degrees is not a "shape" for rain. Do you mean vertical rain is falling? That would be a slope.
Can you not just copy the problem from the book, so we get the correct wording?
It's enough work to solve the problem for the answer, without having to figure out the question as well!
