Question

if a train speed is 95km/h and a man come opposite spped 10km/h and train cross man in 6 second than find length of train

Answer 1

he comes from opposite directions so to get the realative speed both the sweets will be added
(95+10) = 105km/h = 29 m/s

and we know that distance is equal to
speed x time
so
length of train is equal to 29 x 6 = 175 m

show the length of train is equal to 1 75 m

Answer 2

Heya !!

Here is your answer..

$velocity \: of \: train \: = \: 95 \: km \: {h}^{ - 1}$

$velocity \: of \: man \: = - 10 \: km \: {h}^{ - 1}$

P.S : Velocity of man will be negative since it's in opposite direction.

$Relative \: velocity \: = \: 95 - ( - 10) = 105 \: km \: {h}^{ - 1}$

$Or \: relative \: velocity \: = \: 29 \: m \: {s}^{ - 1}$

Now length of train =

$29 \times 6 = 174 \: metre$

Hope it helps.
