Question

A train crosses an electric pole
in 18 sec if the speed of train
is 75 km/h find the length of the train.
​

Answer 1

Answer:

Length of train is 375m

Step-by-step explanation:

Length of train is calculated as

$Length = {Speed\hspace{0.1cm}of\hspace{0.1cm}train \times Time\hspace{0.1cm}taken\hspace{0.1cm}to\hspace{0.1cm}cross\hspace{0.1cm}the\hspace{0.1cm}pole$

Here, we have

Speed of train $= 75km/hr = 75 \times \frac{1000}{3600} = \frac{375}{18}\hspace{0.1cm}$m/s

Time taken to cross electric pole = 18 sec

Hence, length of train is calculated as

$Length = \frac{375}{18} \times 18\\\\ Length = 375\hspace{0.1cm}m$

Length of train is 375m
