Question

solve this with explanation therefore I understand

Answer 1

a simple concept of relative velocity

velocity of train =25km/hr

velocity of man =-2km/hr(since it is in opposite direction )

relative velocity of man with respect to train
25-(-2) =27 kM/hr

relative distance is 270m =0.27km

using relation
$s = ut$
since there is no accelaration

so

0.27=27×t

t=0.27/27=0.01 hr =0.6min=36 second
