Question

The distance from Mercury to the Sun is 28.5 million miles. The distance from Neptune from the Sun is 2.8 billion miles. Express the distance between Mercury and Neptune in scientific notation. Please explain how you came up with the answer.

Answer 1

`2.7715 * {10}^(3) \: million \: miles`

Step-by-step explanation

The distance from Mercury to the sun is 28.5 million miles.

The distance of Neptune from the sun is 2.8 billion miles.

We know that,

1 billion=1000 million.

Therefore,

2.8 billion = 2800 million

The distance between Mercury and Neptune is

2800-28.5 million miles.

=2771.5 million miles

We rewrite this in scientific notation as,

`2.7715 * {10}^(3) \: million \: miles`

or

`2.7715 * {10}^(0) \: billion \: miles`
