One day last summer I cycled through North Yorkshire from Beverley to Whitby, a distance of more than 100 km. It took me more than 10 hours, so you can see that I’m not a very fast cyclist. Rounding the numbers to make the arithmetic easier, I can use the well-known equation:
and conclude that my speed was 100 km/10 h = 10kmh –1. Does this mean I can plot my journey on a graph like Figure 1a?
