Scenario:
“An Ontario hiker has just completed a three-hour hike along this trail. At a number of picturesque locations, the hiker stopped to take photographs. The digital camera recorded the time each photograph was taken. The hiker wants to use these recorded times to pinpoint the locations on a map for a hiking club’s website. Over the three-hour period the hiker travelled nine kilometres and took 5 photographs. The hiker left the trailhead at 9:00 a.m. and took photographs at the following times: 
• Photograph 1 9:15 a.m.
• Photograph 2 9:20 a.m.
• Photograph 3 10:25 a.m.
• Photograph 4 11:20 a.m.
• Photograph 5 11:56 a.m.
Task:
“How far is each photograph location from the trailhead, assuming the hiker walked at a steady pace?”
