• There is no net change in position.
• Distance travelled = 0
• Just the time has changed.

(b) a man, walking on a level, straight and narrow road, with a constant speed.

• Distance is changed at a constant rate.
• The graph will be a straight line inclined to the distance and time axis$.$
• Slope of distance time graph gives speed.
