**Average Speed Calculation**

To calculate the average speed of an object, we need to divide the total distance traveled by the total time taken. In this case, the object travels 16 m in 4 seconds and then another 16 m in 2 seconds.

**Step 1: Calculate the total distance traveled**

The object travels 16 m in the first segment and another 16 m in the second segment. So, the total distance traveled is 16 m + 16 m = 32 m.

**Step 2: Calculate the total time taken**

The object takes 4 seconds in the first segment and 2 seconds in the second segment. So, the total time taken is 4 seconds + 2 seconds = 6 seconds.

**Step 3: Calculate the average speed**

To find the average speed, we divide the total distance traveled by the total time taken:

Average speed = total distance ÷ total time = 32 m ÷ 6 s = 5.33 m/s

Therefore, the average speed of the object is 5.33 m/s.

**Explanation**

The average speed is a way to describe how fast an object is moving over a given distance and time interval. It provides a measure of the object's overall speed during its entire motion.

In this scenario, we have two segments of motion. In the first segment, the object travels 16 m in 4 seconds. This means the object's speed during this segment is 16 m ÷ 4 s = 4 m/s. Similarly, in the second segment, the object covers another 16 m in 2 seconds, resulting in a speed of 16 m ÷ 2 s = 8 m/s.

However, the average speed takes into account the entire motion, not just individual segments. By calculating the total distance traveled and dividing it by the total time taken, we find an average speed of 5.33 m/s.

It is important to note that average speed is a scalar quantity, meaning it only considers the magnitude of the motion, not the direction. In this case, the direction of the object's motion is not mentioned, so we are only concerned with the magnitude of its speed.

Average speed = total distance / total time
16+16/4+2
= 32/6
= 5.33m/s
