An object travels `16 m` in `4 s` and then another `16 m` in `2 s`. What is the average speed of the object?

Options

A. 5.33 m/s
B. 53.3 m/s
C. 4.20 m/s
D. 4.30 m/s

Explanation

To find the average speed of the object, we will follow these steps:

### Step 1: Identify the distances and times
The object travels:
- **First distance (S1)**: 16 meters in **first time (T1)**: 4 seconds
- **Second distance (S2)**: 16 meters in **second time (T2)**: 2 seconds

### Step 2: Calculate the total distance
The total distance traveled by the object is the sum of the two distances:
\[ \text{Total Distance} = S1 + S2 = 16 \, \text{m} + 16 \, \text{m} = 32 \, \text{m} \]

### Step 3: Calculate the total time
The total time taken is the sum of the two times:
\[ \text{Total Time} = T1 + T2 = 4 \, \text{s} + 2 \, \text{s} = 6 \, \text{s} \]

### Step 4: Calculate the average speed
Average speed is calculated using the formula:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{32 \, \text{m}}{6 \, \text{s}} = \frac{16}{3} \, \text{m/s} \approx 5.33 \, \text{m/s} \]

### Conclusion
The average speed of the object is approximately **5.33 m/s**.
