Points (x,y) for months, and corresponding distance in miles. Two points are (0,8) and (x,10), but you do not know this x.

You could recognize that a change rate is given as 0.05 of distance per month.

and using base 10 might be easier.

about 4 months and some fraction of a week.
Maybe 4 months and 2 days; but "4 months" is probably good enough accuracy.
