Understanding the Problem

The moon's diameter is a well-known fact in astronomy, measuring approximately 2,159 miles. However, when dealing with distances in different units, it's essential to convert them to a common unit for accurate calculations. In this case, we're asked to convert the moon's diameter from miles to kilometers, given the conversion factor of 1 mile = 1.6 kilometers.

The Conversion Process

To convert the moon's diameter from miles to kilometers, we can use the given conversion factor. We'll multiply the diameter in miles by the conversion factor to obtain the equivalent distance in kilometers.

Calculating the Diameter in Kilometers

Using the conversion factor of 1 mile = 1.6 kilometers, we can calculate the moon's diameter in kilometers as follows:

2,159 miles × 1.6 kilometers/mile = 3,454.4 kilometers

Evaluating the Options

Now that we've calculated the moon's diameter in kilometers, let's evaluate the given options:

A. 143,042.7 km B. 12,761.5 km C. 2,274.1 km D. 3,454.4 km

Based on our calculation, the correct answer is:

D. 3,454.4 km

Why This Conversion Matters

Converting the moon's diameter from miles to kilometers may seem like a trivial task, but it highlights the importance of using consistent units in scientific calculations. By converting units, we can ensure that our results are accurate and meaningful, which is crucial in fields like astronomy, physics, and engineering.
