Question

Which of the following is not correct?
Distances between two cities are measured in kilometers.

Answer 1

Hint: Here in the above question, we will use the conditions for which we can measure the distance between two cities like which unit will be more suitable for measuring such types of distances. There are certain units like meters, miles, kilometers which we can use.

Complete answer:
The question given to us says if we can measure the distance between two cities only in kilometers or it can be in any other units too.
So, let us take the example of two cities,
And those cities are City A and city B and we also know that the distance between these two cities will be large enough so we need to check what are the units by which we can measure the large enough distances like these of two cities.
And those units which can measure large distances of two cities are kilometers, miles and nautical miles.
So, to say that we can measure the distance between two cities only in kilometers is partially correct and partially incorrect as we have other units like miles and nautical miles to measure these types of distances.
Also, there are other units like meters, centimeters, decimeters, etc. which are used to measure the distances but they are used for smaller magnitudes.
It is not so that we cannot use the above units for measuring larger distances but it will not be convenient for us two measure such a large distance in units like centimeters or meters.
That is why we have this conversion of units so that we can conveniently use such units according to our needs. So as to get the answers in the best way possible.
This will lead to no confusion and assist us in finding the exact answers for the distances given to us for the measurement.

Note:
Here in the above question, we found that the distances between two cities can also be found miles and nautical miles not only in kilometers. So, the question is partially correct as kilometers are not only the unit there are other units too for measuring the distance between two cities.
