Solar winds have an influence all the way to about 160 AU from the Sun. About how many kilometers is that?
Answer
A
24,000,000,000 km
B
48,000,000,000 km
C
240,000,000,000 km
D
480,000,000,000 km
Explanation
One astronomical unit (AU) is about 150,000,000 km. Multiply by 160: 160 × 150,000,000 km = 24,000,000,000 km, so the closest choice is 24,000,000,000 km.
