Question

The position-time (x-t) graph of a particle moving
along x-axis is shown. Average speed of the
particle in time interval t = 0 to t = 20 s is
(1) Zero
(3) 2 m/s
(2) 1 m/s
(4) 4 m/s
​

Answer 1

Answer:

2 m/s

Explanation:

the total distance traveled is 40 m

the total time is 20 sec

as avg speed = distance traveled/total time taken so avg speed =40/20= 2 m/s
