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

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

50km/hr
70km/hr
60km/hr
None

Explanation

Speed of the train relative to man $= (\frac{1 2 5}{1 0}) m / s e c$
$= (\frac{2 5}{2}) m / s e c$
$= (\frac{2 5}{2} \times \frac{1 8}{5}) k m / h r$
$= 45 k m / h r$
Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.
$∴ x - 5 = 45 \Rightarrow x = 50 k m / h r$ .

Explanation

Speed of the train relative to man =(10125​)m/sec=(225​)m/sec=(225​×518​)km/hr=45km/hrLet the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.∴x−5=45⇒x=50km/hr.
