An object travelling in a straight line covers a distance of 100 m from point A to point D in 20 s. The length of the path is divided into three segments AB, BC, and CD. The speed of the object between B and C remains constant but changes between points AB and CD. What is the average speed of the object, and which part of the object's journey is in uniform motion?

Solution : (a) As slope of distance-time graph represents speed of an object, therefore, as is clear from Figure, B has maximum speed, i.e., the object B moves the fastest. (b) For meeting at any point on the road, the respective distance and time values must be same for all the three objects at that point.27 May 2020
