I think what you're looking for is the reverse of this. I think this article gives you the maximum number of flips. I can't find anything about the minimum though. Sorry. Maybe somebody else will find something.

a) On January 1 2000, the park estimated that they had 500 deer on their land. Two years later, they estimated that there were 550 deer on the land. Assume that the number of deer was changing exponentially, i.e. P(t)=ae^bt where P is the number of deer at year t, and a and b are parameters.Find th...

To complete a certain job, B and C (working together) take 50% more days than A, B, and C (working together); for example, if A+B+C take 10 days, then B+C take 15 days. If the 2 take 50% more days then they take 1.5 = 3/2 as long. Let's say it take "d" days to do whatever is "the job...
