What is the speed of the runner on each type of track?
Understand the Problem
The question is asking for calculations related to runner speed based on the provided data for different track types, where the speed needs to be determined using the distance and time.
Answer
- Grass: $ \approx 2.688 \text{ m/s} $ - Gravel: $ \approx 2.924 \text{ m/s} $ - Concrete: $ \approx 3.333 \text{ m/s} $ - Turf: $ \approx 3.030 \text{ m/s} $

- Grass: $ \approx 2.688 \text{ m/s} $
- Gravel: $ \approx 2.924 \text{ m/s} $
- Concrete: $ \approx 3.333 \text{ m/s} $
- Turf: $ \approx 3.030 \text{ m/s} $
Steps to Solve
- Convert Time to Seconds
First, convert the time taken for each track from minutes to seconds.
Use the conversion: $$ \text{Time (seconds)} = \text{Time (minutes)} \times 60 $$
For example, for Grass: $$ 6.2 \text{ minutes} \times 60 = 372 \text{ seconds} $$
- Calculate Speed for Each Track
Next, calculate the speed for each track using the formula: $$ \text{Speed (m/s)} = \frac{\text{Distance (meters)}}{\text{Time (seconds)}} $$
For Grass: $$ \text{Speed} = \frac{1000}{372} \approx 2.688 \text{ m/s} $$
- Repeat for Remaining Tracks
Continue this calculation for Gravel, Concrete, and Turf.
For Gravel: $$ 5.7 \text{ minutes} \times 60 = 342 \text{ seconds} $$ $$ \text{Speed} = \frac{1000}{342} \approx 2.924 \text{ m/s} $$
For Concrete: $$ 5.0 \text{ minutes} \times 60 = 300 \text{ seconds} $$ $$ \text{Speed} = \frac{1000}{300} \approx 3.333 \text{ m/s} $$
For Turf: $$ 5.5 \text{ minutes} \times 60 = 330 \text{ seconds} $$ $$ \text{Speed} = \frac{1000}{330} \approx 3.030 \text{ m/s} $$
- Summarize the Results
Finally, summarize the speeds calculated for each track type.
- Grass: $ \approx 2.688 \text{ m/s} $
- Gravel: $ \approx 2.924 \text{ m/s} $
- Concrete: $ \approx 3.333 \text{ m/s} $
- Turf: $ \approx 3.030 \text{ m/s} $
- Grass: $ \approx 2.688 \text{ m/s} $
- Gravel: $ \approx 2.924 \text{ m/s} $
- Concrete: $ \approx 3.333 \text{ m/s} $
- Turf: $ \approx 3.030 \text{ m/s} $
More Information
This calculation helps understand the speed difference based on track surfaces, which can impact athletic performance.
Tips
- Not converting time to seconds: Always ensure time is in the correct unit for calculations.
- Dividing distance by minutes instead of seconds: Ensure speed is calculated with consistent units (meters/seconds).
