Depends. If the towns are much further, I'd say miles. Acutally, miles all the way. Yards if it's in like spitting distance of yourself XD
i think he means the instrument
i don't exactly know but i would think it's an odometer
The distance between towns is commonly measured in miles or kilometers.
Distances between towns or cities would be measured in kilometre as would long distance runs. A marathon, for example, is approx 40 km. A room would be measured in metres. An average adult male is somewhat short of 2 metres.
The best unit of measurement for the measuring the distance between two towns would be miles. You could also use kilometers if you want, but anything smaller than miles or kilometers would make getting the correct measurement difficult.
A kilometre would be the most appropriate unit.
the measurer
The correct answer would be 40.44.
Light Years.
you would use kilometers.
A ruler
To measure the wavelength of a transverse wave, you would typically measure the distance between two consecutive points that are in phase with each other, such as two crests or two troughs. This distance would represent one full wavelength. Alternatively, you could measure the distance between the start and end points of one complete wave cycle.
The decision when to use kilometers and when to use meters is sort of arbitrary. But usually you would use kilometers when you expect the distance to be close to a kilometer, or larger than a kilometer. For example, distances between towns or cities are often expressed in kilometers.
Km is used for long distances. As the distance between two cities.
