3. In a 36 lap race, each car must make a pitstop which takes 27s and must change tyres from the Soft tyres (which you must start the race on) on to the Medium tyres during the pitstop (which takes a total of 27s). The Soft tyres and the Medium tyres have the same initial pace but each tyre gets slower the longer it is run and suffers degradation. The Soft tyre degrades at 0.20s/lap and the Medium tyre degrades at 0.08s/lap. At the end of which lap should the pitstop be made for the quickest race? *
