Answer 1

To find the distance between Earth and Saturn, we subtract the distance from the Sun to Earth from the distance from the Sun to Saturn:

• Distance from the Sun to Earth: 150,000,000 km
• Distance from the Sun to Saturn: 1,427,000,000 km

Calculating the difference:

1,427,000,000 km - 150,000,000 km = 1,277,000,000 km

Now, we also need to convert this distance to astronomical units (AU):

1 AU = 150,000,000 km

To convert kilometers to AU, we divide the distance in kilometers by the distance of 1 AU in kilometers:

1,277,000,000 km ÷ 150,000,000 km/AU = 8.5 AU

Thus, Earth and Saturn are 1,277,000,000 km apart, which represents 8.5 AU.

The correct response is: 1,277,000,000 km; 8.5 AU.
