Bob and Mark decided to try out for their school's cross-country running team. To discover their level of performance, the coach told them to run 4 km at their fastest steady pace. Each
runner would be timed at 2 minute intervals to see how far they had progressed along the
course. The results for Bob and Mark are recorded in the data table below.
