Answer :
Final answer:
The distance from the Earth to the moon is 3.84e5 km. When converted to miles using the conversion factor of 1 km = 0.621371 miles, it results in approximately 2.38e5 mi, closer to the 1.57e6 mi order of magnitude.
Explanation:
The distance from the Earth to the moon is 3.84e5 km. To convert this distance into miles, you need to use the conversion factor, which is approximately 1 kilometer equals 0.621371 miles. Multiplying the distance by this conversion factor gives:
3.84e5 km * 0.621371 mi/km = 2.38e5 mi.
None of the provided answer choices match this calculation. However, the closest correct order of magnitude would be option 4, which is 1.57e6 mi; the actual numerical value might be slightly different due to rounding in the conversion factor or other approximations.
