Explanation:
Given parameters:
Distance = 125km
Time taken = 2hrs
Unknown:
Speed of the car in km/hr and m/s = ?
Solution:
Speed is the distance divided by the time taken;
Speed = [tex]\frac{distance}{time}[/tex]
So;
Speed = [tex]\frac{125}{2}[/tex] = 62.5km/hr
Now in m/s;
1000m = 1km
3600s = 1hr
So;
62.5 x km x [tex]\frac{1}{hr}[/tex] x [tex]\frac{1000m}{1km}[/tex] x [tex]\frac{1hr}{3600s}[/tex] = 17.36m/s
