John recently traveled from his home town to a distant Conference, on a pedal tricycle of all things! his wonderful, three wheeled tricycle.
He knew that the epic 2,345 mile trip would wreak havoc on the tyres, so, he took along 4 spares!
Instead of waiting for any single Tyre to fail, he decided that he would rotate the tyres evenly, making sure that by the end of the trip all seven tyres had traveled exactly the same distance.
What was the distance that each Tyre traveled ?
