# Clock Puzzle

Sitting uncomfortably in the doctorâ€™s waiting room one day, I stared at the clock on the wall. I had been waiting for what seemed to be a very long time.

To take my mind off the reason for the visit I started to invent little puzzles to solve.

Estimating the length of the minute hand of the clock to be 4 inches, I calculated the distance the hand had travelled around the clock since I arrived to be 15 inches.

How long had I been waiting?

Time = ( 15 / (2*pi*r) ) * 60 min

where, r = 4 inches

Hence time = 36 min, approx

36minutes.
