The car transports 180 m in 12 s. Calculate its speed and express it in m / s and in km / h

Sagot :

Explanation:

Given parameters:

Distance  = 180m

Time  = 12s

Unknown:

Speed  in m/s and km/hr

Solution:

Speed is the distance divided by the time taken,

   Speed  = [tex]\frac{distance}{time}[/tex]  

So;

     Speed  = [tex]\frac{180}{12}[/tex]   = 15m/s

   1000m = 1km

  3600s  = 1hr

Therefore;

   15 x m x [tex]\frac{1}{s}[/tex]  x [tex]\frac{1km}{1000m}[/tex] x [tex]\frac{3600s}{1hr}[/tex]    = 54km/hr
