Given parameters:
Table of values
Planets Average distance from Sun(miles)
Mars 1.42 x 10⁸
Pluto 3.67 x 10⁹
The average distance from Earth to Sun is 93.08 x 10⁶ miles
So:
1 Astronomical unit = 93.08 x 10⁶ miles
Unknown;
Distance in Astronomical unit of Mars and Pluto.
Since :
93.08 x 10⁶ miles = 1 Au
For Mars;
1.42 x 10⁸ miles =
= 0.015 x 10²AU
= 1.5AU
For Pluto:
93.08 x 10⁶ miles = 1 Au
3.67 x 10⁹ miles =
= 0.039428 x 10³AU
= 39.428AU
To the nearest tenth = 39.4AU
So the distance of Mars in AU is 1.5AU and Pluto is 39.4AU
