With a speed of 60 kmph a train crosses a pole in 30 seconds. The length of the train is
|
1000 m 900 m 750 m 500 m |
500 m |
Speed = \(\frac{ Distance}{ Time}\) Let the length of the train be x 60 x \(\frac{ 5}{18 }\) = \(\frac{x}{30}\) 10 x \(\frac{ 5}{3 }\) = \(\frac{x}{30}\) \(\frac{50}{3 }\) = \(\frac{x}{30}\) x = 500 m |
