Which of these is most likely to be
the distance between two cities? 44 kilometers, 2,000 centimeters,
or 84 meters.
In this question, we have to think
about the best unit of measurement to use to measure the distance between two
cities: kilometers, centimeters, or meters. Which is the smallest of these
units of measurement? It’s the centimeter. The width of your index finger is
roughly one centimeter. Can you imagine measuring the
distance between one city and another in centimeters? It would take a very, very long
How about meters? If a baseball bat measures one
meter, would we use meters to measure the distance between two cities? We could, but it would take a very
long time. We use kilometers to measure
distances from one place to another. And it takes about 10 minutes to
walk one kilometer. So this is the best unit of
measurement to use to measure the distance between two cities. So the most likely distance between
two cities is 44 kilometers.
