Question

A cyclist travelling at a uniform speed covers a distance of 9 km in 30 min. Find the speed of the cyclist in m s-¹​

Answer 1

Answer:

the cyclist covered distance = 9km

taken time = 30min

v = s/t

the unit should be there in km/h or m/s

9/(30/60)=9/1/2 = 9.2= 18km/h

by the problem we want change it into ms-¹ or

m/s

so 18km/h × 5/18 = 5m-¹

Answer 2

Explanation:

Distance covered = 9 km = 9000m

Time taken = 30min = 1800 sec

$speed \: = \frac{distance \: covered \: }{time \: taken} \\ speed \: = 9000/1800 \\ = 5 \: \:$

Speed = 5m/s
