D. Hectometer
Explanation
The correct answer is hectometer. "hm" is the symbol for hectometer, which is a unit of length equal to 100 meters. The other options listed (hixameter, hillimeter, hexameter, and hepimeter) are not recognized units of measurement and do not correspond to the abbreviation "hm".
10.
How many meters are there in a hm?
Correct Answer
B. 100
Explanation
A hm stands for hectometer, which is a unit of length in the metric system. The prefix "hecto-" means 100, so a hectometer is equal to 100 meters. Therefore, the correct answer is 100.
11.
Km means what?
Correct Answer
C. Kilometer

It is commonly used in many countries around the world, including those that use the metric system. The abbreviation "km" stands for "kilo-" meaning thousand and "meter" referring to the unit of length. Therefore, kilometer represents a distance of one thousand meters.
12.
How many meters are there in a km?
Correct Answer
B. 1000
Explanation
There are 1000 meters in a kilometer. This is a standard conversion in the metric system, where kilometers are a larger unit of length and meters are a smaller unit. To convert from kilometers to meters, you multiply by 1000. Therefore, the correct answer is 1000.
13.
