A cyclist covers a distance of 750 m in 2 mins 30 Seconds. What is the speed in Km/hr of the cyclist?
Answer & explanation
Correct answer: option 1
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 \(\frac{ 18}{ 5}\)
