If a sprinter runs a distance of 100 metres in 9.83 seconds, write his average speed in km/h.


Distance travelled by the sprinter $d=100\ m$

Time taken $t=9.83\ sec.$

Therefore, average speed of the sprinter $v=\frac{distance}{time}$

$=\frac{100\ m}{9.83\ sec.}$

$=10.18\ ms^{-1}$

Therefore, average speed of the sprinter is $10.18\ ms^{-1}$.
