What is the speed of train if it passes a man running 5km HR?
Let the speed of the train be x km/hr. Then, relative speed = (x – 5) km/hr. x – 5 = 45 x = 50 km/hr.
What is the speed of the train is if it passes a man running at 5 kilometre per hour in the same direction in which the train is going in 10 seconds the train is 125 metre long?
Detailed Solution Time taken = 10 secs. Calculations: Let the speed of train be v km/hr. ∴ The speed of train is 50 km/hr.
Are train to 40 Metre long passes a pole in 24 seconds how long will it take to pass a platform 650 long?
How long will it take to pass a platform 650 m long? m/sec = 10 m/sec. sec = 89 sec.
How many seconds will a caravan 120 Metres long running at the rate 10 m/s take to pass a standing boy?
=72000/3600=20mps. The combined length of platform and train is (l+120)m. The time taken to cross the platform by the train is 23 secs, which can be expressed as:(l+120)/20=23.
How fast does a 125 m long train pass a man?
A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is: Speed of the train relative to man = 125 10 m/sec = 25 2 m/sec = 25 2 × 18 5 km/hr = 45 km/hr Let the speed of the train be x km/hr.
What is the relative speed of man running 5 km/h?
This speed is the speed of the train Relative to the running man.ThereforeRelative Speed = 45 km/h.Speed of man = 5 km/h.But, we know, here,Relative speed = S… Originally Answered: A train 125m long passes a man running 5km/hr in the same direction in which the train is going in 10 seconds.
How fast does a train travel in 10 seconds?
The man sees that a train of length 125 m , passing him in 10 second . u = 50 km/ h. 125 metres in 10 seconds = Travel Rate is 12.5 metres per second x 3,600 seconds = 45 km/h plus an further increase because the man running speed is 5 km/h in the same direction = 50 km/h.
