Quantitative Aptitude ( CCS) Time & distance

A train 100 m long is running at the speed of 30 km/hour. The time taken by it to pass a man standing near the railway line is

7 second

8 second

10 second

12 second

Speed of train V= 30km/hr

Length of train =100m

For crossing a man standing ,train has to cover a distance equal the its length i.e. 100m.

Speed = Distance/Time

Time= Distance/Speed

But both distance and speed should be in same unit system.

V=30 km/hr =(30*1000)/(60*60) m/s

Time = (100*60*60)÷(30*1000)

=36/3= 12 Sec

Hence, option 4 is the correct answer.
