Question

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.

Answer 1

Reggie drives at a speed of 300 km/hr

Explanation:

Answer 2

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 =
`(Distance)/(Time)`

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

Speed =
`(300km)/(1hr)` = 300km/hr

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