B) 1.3 m/s 
C) 0.67 m/s 
D) 0.50 m/s 
E) 0.25 m/s

Quizplus · Accepted Answer

The average speed is calculated by dividing the total distance traveled by the total time taken. If the particle's position at t = 1 s is x1 and at t = 4 s is x4, the average speed is (x4 - x1) / (4 s - 1 s). Based on the given options, 1.3 m/s is the correct average speed.
