What is the speed of a body if it covers a distance of 20 m in 4 seconds?

Explanation

To find the speed of a body that covers a distance of 20 meters in 4 seconds, we can use the formula for speed:

### Step-by-Step Solution:

1. **Identify the Formula for Speed**:
The formula for speed is given by:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

2. **Substitute the Known Values**:
Here, the distance covered is 20 meters, and the time taken is 4 seconds. Substitute these values into the formula:
\[ \text{Speed} = \frac{20 \text{ meters}}{4 \text{ seconds}} \]

3. **Perform the Calculation**:
Now, divide the distance by the time:
\[ \text{Speed} = \frac{20}{4} = 5 \text{ meters per second} \]

4. **State the Final Answer**:
Therefore, the speed of the body is:
\[ \text{Speed} = 5 \text{ m/s} \]
