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.

_______km

Answer 1

`1.29*10^(9)` km

Explanation:

Distance between sun and Saturn:

`1.4*10^(9)`

Distance between sun and Saturn:

`1.1*10^(8)`

So, the Saturn is further than Venus by :

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

`1400000000-110000000`

= 1290000000

=
`1.29*10^(9)` km
