Mathematics Question on Introduction to Graphs
A courier-person cycles from a town to a neighboring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph.
- What is the scale taken for the time axis?
- How much time did the person take for the travel?
- How far is the place of the merchant from the town?
- Did the person stop on his way? Explain.
- During which period did he ride fastest?
Answer
(a) Scale taken for the time axis is 4 units = 1 hour
(b) The person travelled during the time 8 a.m. - 11:30 a.m.
Therefore, the person took 321 hours to travel.
(c) The merchant is 22 km far from the town.
(d) 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.
(e) From the graph, it can be observed 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
