If he were to swim at his personal best pace for the 400m freestyle, how long would it take Ian Thorpe to swim from Australia to New Zealand?
In case you want to clarify, we will assume that he swims on a straight line from Bondi Beach in Sydney to Manukau Heads in Auckland, and doesn’t get put off course by currents or attacked by sharks or have to stop for meals. (Yes, we know this is wildly impractical. We also don’t care.)
