Question

solar winds have an influence all the way to about 160 au from the sun. about how many kilometers is that?
24,000,000,000 km
48,000,000,000 km
240,000,000,000 km
480,000,000,000 km

Explanation:

Step1: Define 1 AU value

1 astronomical unit (AU) ≈ $1.5 \times 10^8$ km

Step2: Calculate total kilometers

Multiply 160 by $1.5 \times 10^8$ km:
$160 \times 1.5 \times 10^8 = 240 \times 10^8 = 24,000,000,000$ km

Answer:

24,000,000,000 km
