Solution
Solution Steps
Step 1: Identify the Given Values
Distance: 40 yards
Time: 5 seconds
Step 2: Recall the Formula for Average Speed
The formula for average speed is given by:
\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]
Step 3: Substitute the Given Values into the Formula
Substitute the given values into the formula:
\[
\text{Average Speed} = \frac{40 \text{ yards}}{5 \text{ seconds}}
\]
