Solution
- Scale taken for the time axis is 4 units = 1 hour
- Time taken by a person for the travel = `(1+1+1+1/2) "hours" = 3 1/2` hours.
- The merchant is 22 km from the town.
- Yes, the person stopped on his way from 10 a.m. to 10: 30 a.m. This is indicated by the horizontal part of the graph.
- From the graph, it canfromserved that during 8 a.m. to 9 a.m., the person travelled the maximum distance. Thus, the person’s ride was the fastest between 8 a.m. and 9 a.m.
