Answer :
Given parameters:
Distance covered by Reggie = 300km
Time taken = 1hour
Unknown parameter:
Speed of Reggie in km per hour = ?
Speed is a physical quantity which is classified as a scalar parameter. As a scalar, speed has magnitude but no directional attribute.
Also, speed is the rate of change of distance with time.
Mathematically;
Speed = [tex]\frac{Distance}{Time}[/tex]
Now, to solve for speed, input the parameters given.
Speed = [tex]\frac{300km}{1hr}[/tex] = 300km/hr
Therefore, Reggie drives at a speed of 300km/hr
