Driving at a constant speed, Reggie travels 300 kilometers in 1 hour. What is Reggie’s speed in kilometers per hour?

Reggie drives at a speed of
kilometers per hour.

Reggie drives at a speed of 300 km/hr

Step-by-step explanation:

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  =

Now, to solve for speed, input the parameters given.

           Speed  = = 300km/hr

Therefore, Reggie drives at a speed of 300km/hr
