Cratering evidence throughout the Solar System indicates that the frequency of asteroid impact is inversely proportional to the cube of the diameter of the asteroid (that is, 1/D³).The 2013 Chelyabinsk meteor was around 20 meters in diameter and impacts of this size are expected once every 60 years, on average.If the Tunguska impact was a meteor around 100 meters in diameter, what is the expected average time between impacts of that size? A) 1 every 220,000 years B) 1 every 7,500 years C) 1 every 1,200 years D) 1 every 180 years E) 1 every 0.5 year (2 a year)
