Question

If a sprinter runs a distance of 100meterin9.83second calculate his average speed in km/h?

Answer 1

Answer:

Hii mate,

Speed = Distance / Time

Explanation:

As per given,

Distance = 100m and Time = 9.83 s

Speed = 100/9.83 = 10.17 m/s

[ Remember this

1. m/s to km/ hr - multiply by 18/5

2. km/hr to m/s - multiply by 5/18 ]

In this problem, we should multiply by 18/5

So, 10.17*(18/5) = 36.61 km/hr

Hence the answer. I hope you understand.
