Question

A train is moving at 40km/h and take 18 seconds to cross a pillar then what is the length of train

Answer 1

Hiii...
Here is your answer...

Solution:-
Speed= 40km/h
$= > 40 \times \frac{5}{18} \\ = > \frac{100}{9}$
Time= 18 seconds

Now,
Length of train(Distance)=Speed×Time
$= > \frac{100}{9} \times 18 \\ = > 200m$
Hence,the length of train is 200m.
