 Hello and welcome to the session. In this session we will discuss a question which says that Lara walks to her friend's house and to get him to hire a cab to the mall, they stop once before arriving at the mall, drop a graph to describe Lara's journey from home to shopping mall. Now before starting the solution of this question, we should know a result. And that is for journey we use time distance graph and for faster speed the graph is steeper and for stoppage we drop a horizontal line. Now here you can see line segment AB is steeper which represents faster speed and line segment BC is horizontal which represents stoppage. Now these results will welcome to the key idea for solving out the given question. Now let us start with the solution of the given question. Now we have to drop a graph to describe Lara's journey from home to shopping mall and from key idea we know that for journey we use time distance graph. So here as we have to describe a journey so we will make use of time distance graph and here we will take distance from vertical axis and time on horizontal axis. Now we are given that Lara starts from home and walks to her friend's house so her speed will be constant. So the graph will start with a steady straight line. Now we mark O for the starting point and this is the point from where Lara starts her journey that is from her home from this point she moves to her friend's house. Now let that point be A. Now since her speed is constant so the graph will be a steady straight line from point O to A. Now at her friend's house she stays for a while and from the key idea we know that for stoppage we use a horizontal line. Now at her friend's house she has a stoppage so we will use a horizontal line here and after this both of them hire a gap. Now when her speed will be higher so after this stoppage we will draw a line to represent faster speed. Now from key idea we know that for faster speed graph is steeper so we make a steeper straight line and reach the point B where they start for some time. Now again at this point they have a stoppage so we will draw a horizontal line here. Now from this point let's if we see they start in tab again. Now we draw a steeper straight line from the point C at the point D. So this is the graph which describes Lara's journey from home at point O shopping mall at the point so we can write Lara starts from home at the point O and reaches her friend's house at point A. They together hire a gap they reach point B in less time and then they stop for some time and again from point C and reach mall at point T. This is the journey with the help of a graph and this completes our session. Hope you all have enjoyed the session.
