18.Answer
i) So to find the position of the object at time 20 second, we draw a line parallel to y-axis from time 20 and take the point where it intersects then again draw a line parallel to the x-axis, we get the distance where it intersects the y-axis.
Here the position is 8 meters from starting.
ii) Distance travel in 12 seconds by the object is 6 meters.
iii) Since average speed of object is define as total distance covered by object by total time take. So here total distance is 8 m and the total time is 20 second,
Average speed =
= 0.4 m/s
