Pls help me answer 2.2.3 and 2.2.4
(2.2.4 needs to be converted)
ill give brainstorm

Analysis of graph :-

We have given one graph which is plot between distance and time. where time is in minutes and distance is in seconds.

According to the graph

For the first 5 minute ( O to A) , The distance is continously increasing 2m / per minute . For the 5 minute that is from 5 minute to 13 minute ( A to B) both marellize and her dog wally moving with the constant speed .For next 3 minutes that is from 10 minutes to 13 minutes ( B to C) , The distance is continously decreasing with time .For next 3 minutes that is from 13 to 16 minutes ( C to D) , Again they moved with constant speed .For next 6 minute that is from 16 to 21 minutes ( D to E) . Again, There distance is increasing with time .Again For next 4 minutes that is 21 to 25 minutes , they are moving with constant velocity .Let's Begin :-

1) Between O and A

The marellize and wally when moving between O to A , The distance is constantly increasing with time. The graph is Straight line

2) Between A and B

The marellize and wally when moving between A to B, The distance remains the same with time that is they moving with constant speed. The graph is constant or steady

3) Between B to C

The marellize and wally when moving between B to C, The distance is constantly decreasing with time .The graph is straight line but it follows decreasing function .

4) For covering the First 6 km ,

According to the graph,

For covering first 6 km, They took 3 minutes.

5) No, Marellize and wally walk does not from where they have started.

According to the graph

It is end at 5 m instead of 0m .
