Distance–Time Graph of Gary’s and Garion’s Journeys Between Towns P and Q
TGM Original Questions
The graph shows the journeys of Gary and Garion between Towns \(P\) and \(Q\) which are \(25\) km apart.
Using the graph,
- find the distance Gary was from Town \(Q\) when he stopped for a rest,
- find the amount of time Gary took to rest,
- state the time Garion overtook Gary,
- find the distance between the two boys at \(1050\),
- calculate the average speed for Garion’s whole journey.
Editorial clarification: the printed leftmost time label is inconsistent with the uniform scale marked 1100 and 1200. Use that uniform scale throughout; the leftmost origin then corresponds to 1000.
