The average speed is (distance)/(time) = 300m / 2min. That's 150m per minute, or 2.5m per second. The average velocity is (displacement)/(time) = (distance from the start point to the end point regardless of the route)/(time)= zero.

Answer:

<h2>The average speed is 1.5 meters per second.</h2>

Explanation:

Givens

Bicycle traveled a distance of 150 meters, twice, from point A to B, and from B to A.
The time it took to return to point A is 2 minutes, which is 120 seconds.

Basically, the bicycle traveled a total of 300 meters using 4 minutes, assuming that is a constant movement. So, the average speed is

$s=\frac{300m}{4(60sec)}=1.25 m/s$

Therefore, the average speed is 1.5 meters per second.
