D= 100m
Δt = 9,86s
-------------------------/
Viteza medie
------------------------//

V =  \frac{Distanta}{TImp}

V= \frac{100}{9,86} = 10,14 m/s

10,14 \frac{m}{s} = 10,14*   \frac{1/1000Km}{1/3600} =   \frac{10,14/1000}{1/3600} =  \frac{10,14}{1000} *  \frac{3600}{1}   =  \frac{36504}{1000}  \\  \\ =36,504km/h

SAU se mai putea face asa :

Daca intr-o secunda face 10,14m/s => o ora = 10,14*3600 = 36504m/h = 36,504km/h 

Recomand prima varianta pentru siguranta maxima.
