The first thing you should learn when studying astronomy is that it is not astrology. Astrology is not a science. Objects weigh about 1/6 as much on the moon as they do on Earth.

At a more northern latitude, but still in the southern hemisphere. Figure out how many degrees of longitude correspond to 100 km and add it to -45. It's roughly one degree. Is this really what they are considering astronomy these days?

This sounds more like geology (or planetary studies) than astronomy. Presumably the direction of plate motion changed where there is a bend in the chain. So.. Divide 4000*10^3 m by 0.08 m/year. You get 50 million years.

Intro to Astronomy
If 1% is left, (0.01) = (0.5)^N where N is the number of half-lives. N = 6.644 minimum age = 37,900 years There will be less than 1% left if the sample is older than that, so that is a minimum age. There is not much about astronomy here
