A cyclist covers a distance of 750 m in 2 mins 30 Seconds. What is the speed in Km/hr of the cyclist?

18

Speed = \(\frac{ Distance}{ Time}\)

Speed = \(\frac{ 750}{ 150}\) m/s

Speed = 5 m/s

Speed in km/hr - 5 x \(\frac{18 }{5 }\) = 18 km/hr

*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  \(\frac{ 18}{ 5}\)
