Sam drove from Oxford to Manchester. He made one stop at a motorway service station.
Here is part of Sam's travel graph.

A travel graph showing distance from Oxford in miles against time. The y-axis ranges from 0 to 200 with major grid lines every 20 units and minor grid lines every 10 units. The x-axis shows times from 09 00 to 15 00 with major grid lines every hour and minor grid lines every 15 minutes. The graph consists of three straight line segments: from (09 00, 0) to (11 00, 80), from (11 00, 80) to (11 30, 80), and from (11 30, 80) to (12 15, 110).
