In the groove

I invested in some lateral thinking exercises, and being the amazing lateral thinker I am, i thought I’d get you lot to solve them for me!

A Vinyl record measures 32cm across. There is a 1cm margin around the edge and a centre label which measures 10cm across. There are 30 grooves per cm. How far does the needle travel if the record is played from start to finish?

  1. Hehe… this is the same answer I originally had. Unfortunately it is incorrect. I wonder what Aristotle thinks of you using his name all the time…WARNING: HINT BELOW.Whilst the needle does not move around the record, it does move from the outside to the inside of the record…

  2. for a lateral thinker you are stuck in the groove.the needle DOES NOT TRAVEL ANYWHERE, the vinyl record spins on the turntable.
