Question

The number of years N(r) since two independently evolving languages split off from a common ancestral language is approximated by N(r) = - 5000 ln r, where r is the proportion of the words from the ancestral language that are common to both languages now. a) How many years have elapsed since the split if 20% of the words of the ancestral language are common to both languages today? b) If two languages split off from a common ancestral language about 2000 years ago, find r.
