D. The average speed is 2.5 m/s and the average velocity of the bicycle is 0 m/s east.
<h3>
What is average speed?</h3>
The average speed of an object is the ratio of total distance to total time of motion of the object.
average speed = total distance traveled / total time taken
average speed = (150 m + 150 m) / (2 mins x 60s/min)
average speed = (300 m) / (120 s)
average speed = 2.5 m/s
<h3>What is average velocity?</h3>
The average velocity of an object is the ratio of change in displacement to change in time of motion.
v = Δx/t
v = (150 m - 150 m) / (120 s)
v = 0 m/s
Thus, the average speed is 2.5 m/s and the average velocity of the bicycle is 0 m/s east.
