Answer:
5000
Explanation:
Measurements can be given in multiple units. Unit conversion is important, especially when dealing with formulas because sometimes only specific units work.
Metric System
In this case, the question is asking about kilometers (km) and meters (m), both of which are in the metric system. Unit conversions are easier in the metric system because it uses prefixes that give you extra information. Each of the prefixes means a different number.
- Milli - 1/1000th
- Centi - 1/100th
- Deci - 1/10th
- Deca - 10
- Kilo - 1000
These are not all of the possible prefixes, but they are the most common. This means that a decameter represents 10 meters and 1 millimeter is 1/1000 of a meter.
Conversion
Using the prefixes above, we can tell that 1 kilometer is 1000 meters. So, we can multiply whatever amount of kilometers we have by 1000. This will gives the number of meters.
Thus, 5 km = 5000 m.
