Practicing Success
A train moves with a speed of 108 kmph. Its speed in meters per second is :
|
38.8 18 30 None of these |
30 |
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 |
