Running

Runners are always keeping track of their running times, whether it is during training or in competition. They sometimes use apps, such as the running log shown here, to do most of the data collection.

  1. The running log shows an interesting rate: minutes/mile or "pace." Explain what this is.
  2. The running log shows data for 10 runs. Which run was the fastest in terms of speed?

    Run 53 shows a pace of 10:30 minutes per mile. John wants to maintain this pace for his next competition run, which is 8 miles long. He makes this running schedule table to be sure he runs exactly at that pace.

  3. Open and complete the running schedule table.
  4. Draw the graph of John's intended run with time as independent variable.
  5. This table contains the data from John's actual run.
  • Draw a graph for the actual run in the same coordinate grid that you used to graph the intended run. Describe what happened during John's run.
  • What was his average speed?
