Question

A cyclist covers a distance of 750m in 2min30sec.what is the speed in km/hr of the cyclist

Answer 1

distance covered by cyclist = 750 m
time taken = 2min 30sec =150 sec

we know,
speed = distance/time
= 750 m/150 sec
= 5 m/sec
we know,
m/s change to km/h when 18/5 multiply with m/s

so, speed = 5m/s = 5× 18/5 = 18 km/h

Answer 2

A cyclist covers a distance of 750m.
Time taken = 2min30sec = 150 s
Speed = 750/150 m/s = 5 m/s = 5 × 18/5 km/hr = 18 km/hr
