Question

the annual beach run is 5.2 x 10⁵m. what is the best unit of measure of express this? metrics (equivalent) 1 meter 100 cm 1000 mm.001 km

Explanation:

Step1: Understand the given length

The length of the beach run is \( 5.2\times10^{5}\, \text{m} \). Let's calculate its value: \( 5.2\times10^{5}=520000\, \text{m} \).

Step2: Convert to kilometers

We know that \( 1\, \text{km} = 1000\, \text{m} \), so to convert meters to kilometers, we divide by 1000.

$$ \frac{520000}{1000} = 520\, \text{km} $$

Using kilometers makes the number more manageable and is a more appropriate unit for such a large distance (a beach run of 520000 meters is 520 kilometers, which is a reasonable way to express this length compared to using meters, centimeters, or millimeters).

Answer:

Kilometer (km)
