Thought id stick a few questions up for anyone whos bored, i know chip likes stuff like this so it can give you a bit brain workout

Ill start with a nice easy one first


A hiker walks from one town to another. On the first day she covers one quarter of the total distance.

The next day she covers one quarter of what is left.

The following day she covers two fifths of the remainder and on the fourth day half of the remaining distance.

She now has 15 miles left. How many miles has she travelled?
