Question

The table shown below gives the approximate distance from the sun for a few different planets. How much further (in km) from the sun is Saturn than Venus? Express your answer in scientific notation.

Answer 1

1.29 * 10^9.

Explanation:

That is 1.4 * 10^9 - 1.1 * 10^8

= 14 * 10^8 - 1.1 * 10^8

= 12.9 * 10*8

= 1.29 * 10^9.

Answer 2

Saturn is
`1.29*10^(9)` Km further from the Sun than Venus.

Explanation:

We want to determine how far is Saturn than Venus from the Sun. We have to compare the distance of the two planest from the Sun.

The distance of Saturn from the Sun is
`1.4 * 10^(9)` Km

The distance of Venus from the Sun is
`1.1 * 10^(8)` Km

How much further (in km) from the sun is Saturn than Venus = distance of Saturn from the Sun - distance of Venus from the Sun

=
`1.4 * 10^(9)` -
`1.1 * 10^(8)`

= 1290000000

=
`1.29*10^(9)` Km

Therefore, Saturn is
`1.29*10^(9)` Km further from the Sun than Venus.
