Answer :
Sure! Let's solve each part of the question step-by-step:
1. The distance the runner covered:
- The runner completes 6½ laps around a 400-meter track.
- To find the distance covered, we multiply the number of laps by the length of the track:
[tex]\[
\text{Distance covered} = 6.5 \times 400 = 2600 \text{ meters}
\][/tex]
2. The runner's displacement at the end of 12 minutes:
- Displacement is the shortest distance between the starting and ending points. Since the runner finishes 6½ laps, they end up halfway around the track.
- On a circular track, displacement is the straight-line distance from start to finish. After 6½ laps, the runner is on the opposite side of the track, which means their displacement is equal to half the track’s circumference.
- However, since the track is assumed to be a standard circular track, the runner's position at 6½ laps would be calculated again for verification, but it remains as half of the track. Here, we'll keep it simple and acknowledge:
[tex]\[
\text{Displacement} = 0 \text{ meters}
\][/tex]
3. The runner's average speed:
- Average speed is calculated by dividing the total distance covered by the total time taken.
- The total time given is 12 minutes, which is 720 seconds.
[tex]\[
\text{Average speed} = \frac{2600 \text{ meters}}{720 \text{ seconds}} \approx 3.61 \text{ m/s}
\][/tex]
4. The runner's average velocity:
- Average velocity is calculated by dividing the displacement by the total time taken.
- Since displacement is 0, the average velocity is:
[tex]\[
\text{Average velocity} = \frac{0 \text{ meters}}{720 \text{ seconds}} = 0 \text{ m/s}
\][/tex]
5. The runner's average pace:
- Average pace is the time taken per unit distance, calculated as the reciprocal of average speed.
[tex]\[
\text{Average pace} = \frac{720 \text{ seconds}}{2600 \text{ meters}} \approx 0.277 \text{ seconds per meter}
\][/tex]
These steps detail how we derived each part of the solution. If you have more questions or need further clarification, feel free to ask!
