Question

From the v - t graph shown. the ratio of distance to displacement in 25 s of motion

(1) 3/5 

(2) 1/2 

(3) 5/3 

(4) 1

Answer 1

Correct option is (3) 5/3

Area under the graph from t = 0 to t = 20 sec = 200 m 

Area under the graph from t = 20 to t = 25 sec = 50 m 

So distance covered = (200 + 50)m = 250 m 

Displacement = (200 - 50)m = 150 m

250/150 = 5/3
