if a sprinter runs a distance of 100 M in 9.83 seconds calculate his average speed in kilometre per hour
sprinter runs 100m in 9.83 sec
we know that formula of speed: distance /time
100m/9.83 sec
![= 10.17 = 10.17](https://tex.z-dn.net/?f=+%3D+10.17)
we know in 1 km /1000m and 1 hour 3600 sec
![1000 \div 3600 = 18 \5 1000 \div 3600 = 18 \5](https://tex.z-dn.net/?f=1000+%5Cdiv+3600+%3D+18+%5C5)
avarage speed ;distance/time
![18 \5 \times 10.17 = 36.62 answer 18 \5 \times 10.17 = 36.62 answer](https://tex.z-dn.net/?f=18+%5C5++%5Ctimes+10.17+%3D+36.62+answer)
