Question 18

Distance-time graph of an object is given below.

(i) What will be the position of the object at 20s?
(ii) What will be the distance traveled by the object in 12s?
(iii) What is the average speed of the object?

Answer 1

(i) As you look at the graph, 20 seconds on X-axis corresponds to 8 m
(ii) 12 seconds on X-axis corresponds to 6 m
(iii) Average Speed = Total distance / Total time = 8/20 = 0.4 m/s.
