Inches. Just kidding, miles.
You can't measure that..... Los Angeles is already in California!
Any of those units could be used. 'Kilometers' would result in the most convenient number.
The most appropriate unit of length for measure the distance between Las Vegas and Los Angeles would be either miles or kilometers.
A global positioning system (GPS)
The most appropriate unit of length for measure the distance between Las Vegas and Los Angeles would be either miles or kilometers.
Angstroms
With maths and light brightness.... Distance between two points...
The distance between places.
the measure of a straight-line distance between two points is called length.
By using the distance formula between two coordinated points
Let's say we want to measure the distance between objects A and B. First, we measure the distance from the Earth(point E) to these objects(using Doppler-shifts).Then, we measure the angle AEB.We now know the lengths of two sides, and the angle between them. That's how we find the distance AB.
To measure the distance between Chicago and Miami it would be appropriate to work in miles, since the US generally uses imperial measurements. However, it would also be appropriate to also list the kilometer equivalent to the mile measurement, since a person accessing the data might be more familiar with the metric system of measurement.
