A Kilometre is a mid range unit of linear distance. It is used mainly to indicate the separation of places geographically.

Five things commonly measured in kilometers include the distance between cities, the length of hiking trails, the span of a marathon (42.195 kilometers), the circumference of large geographical features like lakes, and the altitude of high mountains (often expressed in kilometers above sea level). Kilometers are a standard unit of measurement in many countries for both land and air travel.
Divide speed by time. In this case, you get (kilometers / hour) / hour, or kilometers/hour2. That means, how much does the speed change in an hour.
Scalars are quantities that have magnitude but no direction. Common examples in daily life include temperature (e.g., 25 degrees Celsius), mass (e.g., 70 kilograms), and time (e.g., 30 minutes). These quantities can be measured and expressed with a number but do not indicate any specific directionality. Other examples include speed (e.g., 60 kilometers per hour) and distance (e.g., 5 kilometers).
