An object travels 20 m in 10 s. What is the average speed of the object ?

Explanation

To find the average speed of an object that travels a certain distance in a given time, we can use the formula for average speed:

### Step-by-Step Solution:

1. **Identify the Distance Traveled (D)**:
- The object travels a distance of 20 meters.
- So, \( D = 20 \, \text{m} \).

2. **Identify the Time Taken (T)**:
- The time taken to travel this distance is 10 seconds.
- So, \( T = 10 \, \text{s} \).

3. **Use the Formula for Average Speed (v)**:
- The formula for average speed is given by:
\[ v = \frac{D}{T} \]
- Where \( v \) is the average speed, \( D \) is the distance, and \( T \) is the time.

4. **Substitute the Values into the Formula**:
- Substitute \( D = 20 \, \text{m} \) and \( T = 10 \, \text{s} \) into the formula:
\[ v = \frac{20 \, \text{m}}{10 \, \text{s}} \]

5. **Calculate the Average Speed**:
- Perform the division:
\[ v = 2 \, \text{m/s} \]

6. **Conclusion**:
- The average speed of the object is \( 2 \, \text{m/s} \).
