A train moves with a speed of 108 kmph. Its speed in meters per second is :
Answer & explanation
Correct answer: option 3
Speed = \(\frac{ Distance}{ Time}\)
*Note*
In order to convert km/hr to m/s - multiply by \(\frac{ 5}{ 18}\)
In order to convert m/s to kn/hr - multiply by \(\frac{ 18}{ 5}\)
Thus,
108 x \(\frac{5 }{18 }\) = 30 m/s
