Verified step by step guidance1
Understand the unit conversion: 1 megameter (Mm) is equal to 1,000 kilometers (km).
Identify the given value: The earth's circumference is 40.1 Mm.
Set up the conversion: Multiply the number of megameters by the conversion factor to convert to kilometers. This means you will multiply 40.1 Mm by 1,000 km/Mm.
Perform the multiplication: Calculate 40.1 multiplied by 1,000 to find the circumference in kilometers.
Interpret the result: The calculated value will give you the earth's circumference in kilometers, which should match the correct answer provided.
