A courier-person cycles from a town to a neighbouring suburban area to deliver a parcel to a merchant. His distance from the town at different times is shown by the following graph :

**(a)** What is the scale taken for the time axis?

**(b)** How much time did the person take for the travel?

**( c)** How far is the place of the merchant from the town?

**(d)** Did the person stop on his way? Explain.

**(e)** During which period did he ride fastest?

In the graph, we find that the time (in hours) is represented on the x-axis and the distance (in km) is represented on the y-axis. The distance at any time can be read from the graph exactly in the same way as we read the coordinates of a point. From the graph, we observe that :

**(a)** The scale taken for the time axis is : 4 units = 1 hour.

**(b)** The person took 3 hours for the travel.

**( c)** The merchantâ€™s place from the town is 22 km.

**(d)** Yes; this is indicated by the horizontal part of the graph (10 a.m. -10.30 a.m.)

**(e)** Between 8 a.m. and 9 a.m. he ride faster.
