The distance from Earth to the Moon is approximately 240,000 mi. (a) What is this distance in meters?

검증된 단계별 안내

insert step 1> Start by identifying the conversion factor between miles and meters. You know that 1 mile is equal to 1,609.34 meters.

insert step 2> Set up the conversion by multiplying the distance in miles by the conversion factor to convert it to meters.

insert step 3> Write the equation: \( \text{Distance in meters} = 240,000 \text{ mi} \times 1,609.34 \text{ m/mi} \).

insert step 4> Perform the multiplication to find the distance in meters.

insert step 5> Ensure that your final answer is in the correct units, which should be meters.
