Each question is a journey in words. Step 1: draw its graph by tapping the grid at each corner. Step 2: use the graph to answer the questions: gradients give speeds and accelerations, areas give distances.
Questions in a round:
Read the journey, draw its graph on the grid, then answer the questions from the graph.
