Question

Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury

Answer 1

9514 1404 393

Answer:

Explanation:

The ratio of distances is ...

Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)

= 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7

Neptune is about 77.76 times as far from the Sun as Mercury is.
