Question

A 100 m long train is moving at a speed of 60 kmph . In what time will it cross a sign pole.​

Answer 1

Answer:

Train 100m long and moving with velocity 60km/hr=60×  5/18

​  

m/sec= 50/3 m/ sec.

​  

We have to find time train will take to cross a brige 1km i.e 1000m long.

Length of train be lt , length of bridge be lb and velocity of train be v

So time taken =  

v

lt+lb/v

​  

 

                 

 

​  

 

100+1000/3 upon 5

​  

 

                 =66sec
