Question

Practice Problems 1 : 1. A cyclist covers a distance of 50 m in 10 s. Calculate the speed of the cyclist in (i) m/s (ii) km/h.​

Answer 1

(we know that speed=distance/time)

( i ) speed of cyclist in m/s

= 50/10=5m/s

( ii ) speed of cyclist in km/h = 50/1000/10/3600=0.05/1/360=0.005km/h

therefore, your answer is ( i ) =5 m/s ( ii ) = 0.005 km/h
