helpful to sketch and label a diagram. Please round your answer to the 100,000's place

Answer 1

The average distance from Earth to the Moon is 383,000 km after rounding to the nearest 100 km. The distance from Earth to the Sun is about 148,900,000 km when rounded to the nearest 100,000 km. The distance between the Moon and the Sun, when the Moon is between them, is 148,500,000 km after rounding.

Step-by-step explanation:

To convert the average distance from the Earth to the Moon from miles to kilometres, we use the conversion factor that 1 mile is approximately equal to 1.60934 kilometres.

• Earth to the Moon: 238,000 miles * 1.60934 km/mile = 383,020.92 km, rounded to the nearest 100 km gives 383,000 km.
• Earth to the Sun: 92,600,000 miles * 1.60934 km/mile = 148,904,284 km, rounded to the nearest 100,000 km gives 148,900,000 km.
• Distance between the Moon and Sun when the Moon is between the Earth and Sun: Assuming the Moon is at an average distance from Earth, we subtract the distance of the Moon from Earth from the distance of the Earth from the Sun:

148,900,000 km - 383,000 km = 148,517,000 km, rounded to the nearest 100,000 km, gives 148,500,000 km.
