Question

Venus is an average distance of 108.2 million kilometers from the sun. Use the conversion factor 1 AU = 1.5 x 10^8 km to convert this distance from kilometers to astronomical units.

a) 0.7213 AU
b) 0.7216 AU
c) 0.7218 AU
d) 0.7220 AU

Answer 1

The average distance from Venus to the Sun is 108.2 million km. Using the conversion factor 1 AU = 1.5 x 10^8 km, this distance converts to 0.7213 AU.

Step-by-step explanation:

To convert the average distance from Venus to the Sun from kilometers to astronomical units (AU), we can use the given conversion factor of 1 AU = 1.5 x 108 km. We divide the distance of Venus from the Sun, 108.2 million km, by the value of 1 AU in kilometers.

Here's the calculation:

• Distance of Venus from the Sun = 108.2 million km = 108.2 x 106 km
• 1 AU = 1.5 x 108 km
• Conversion to AU = (108.2 x 106 km) / (1.5 x 108 km)
• Conversion to AU = 108.2 / 150 = 0.7213 AU

Therefore, the average distance of Venus from the Sun is 0.7213 AU.
