Question
How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr?
Answer: Option B
- Speed of the train relative to man = (63 - 3) km/hr
= 60 km/hr = 60 x 5 m/sec 18 = 50 m/sec. 3 Time taken to pass the man = 500 x 3 sec 50
= 30 sec.
