A bicycle traveled 150 meters west from point A to point B. Then it took the same route and came back to point A. It took a total of 2 minutes for the bicycle to return to point A. What is the average speed and average velocity of the bicycle?

average speed is total distance/total time = (150+150)/2 = 150 m/min

average velocity is zero, since the final location is the same as the starting location.

To find the average speed and average velocity, we need to calculate the total distance traveled and the total time taken.

First, let's calculate the total distance traveled. Since the bicycle traveled 150 meters west from point A to point B and then returned to point A, the total distance traveled is 150 meters + 150 meters = 300 meters.

Next, let's calculate the total time taken. We are given that it took a total of 2 minutes for the bicycle to return to point A.

To find the average speed, we divide the total distance traveled (300 meters) by the total time taken (2 minutes):

Average Speed = Total Distance / Total Time
Average Speed = 300 meters / 2 minutes

To simplify the units, let's convert the time from minutes to seconds. There are 60 seconds in 1 minute.

Total Time in seconds = 2 minutes * 60 seconds/minute
Total Time in seconds = 120 seconds

Average Speed = 300 meters / 120 seconds
Average Speed = 2.5 meters/second

The average speed of the bicycle is 2.5 meters/second.

Now let's calculate the average velocity. Velocity is a vector quantity that takes into account both speed and direction. Since the bicycle traveled 150 meters west and then returned to point A, its average velocity will be zero because it returned to its starting position.

Therefore, the average velocity of the bicycle is zero.
