Question

the distance between planets varies as they move in their orbits. the minimum distance from the earth to mars is about 0.35 au. about how many kilometers is that? 15,000,000 km 25,000,000 km 55,000,000 km 70,000,000 km

Explanation:

Step1: Recall the conversion factor

1 AU (Astronomical Unit) is approximately 149597870.7 km.

Step2: Calculate the distance in km

Multiply 0.35 AU by the conversion factor: $0.35\times149597870.7 = 52359254.745\approx55000000$ km (approximate value for a closer - match with given options).

Answer:

55,000,000 km
