Problem

The two graphs below depict the same journey along a straight road.

  • What’s the same and what’s different about the graphs?
  • What do you think the labels on the each of the axes would be?
Curve increases to 8, stays roughly constant, then increases to 16.
Curve increases to 8, stays roughly constant, then decreases to 0.
  • What sort of things do we measure when taking a journey? Which axis are these likely to go on?

  • If you walk to school, and then home again, how far have you walked and how far have you moved from your starting point?
