For counting x you use simple equation for the distance covered by the object when it moves with constant velocity:
that gives you 20m after 1st second, 40 m after 2nd second, 60 m after 3rd second and so on.
For counting y you have to use the equation for the distanced covered by the object moving with constantly accelerating velocity (symbols refering to vertical movement):
that gives you 5m after 1st second, 20m afters 2nd second, 45m after 3rd second and so on.
Add minus signs before y positions to receive graph presenting the movement of the ball.
So the points are: P1=[20,-5], P2=[40,-20], P3=[60,-45] and so on... Pn=[x,y].
that gives you 20m after 1st second, 40 m after 2nd second, 60 m after 3rd second and so on.

<h2>The average speed for the entire trip is 47.5 m/s .</h2>
It is given that for different time span car have different speed and also the person spend in eating lunch and buying gas.
We know , average speed is total distance covered by total time taken .
Therefore , average speed ,
Hence, this is the required solution.
