Solution:
1. Convert the speed limit to meters per second.
- The speed limit is 30 km/h.
- Convert km/h to m/s:1 \text{ km/h} = \frac{1}{3.6} \text{ m/s}
- Therefore,30 \text{ km/h} = 30 \times \frac{1}{3.6} \text{ m/s} = \frac{30}{3.6} \text{ m/s} = 8.33 \text{ m/s}
2. Compare the speeds of cars A, B, and C to the speed limit.
- Speed of car A:8 \text{ m/s} 8.33 \text{ m/s}
- Speed of car B:9 \text{ m/s} 8.33 \text{ m/s}
- Speed of car C:10 \text{ m/s} 8.33 \text{ m/s}
3. Conclusion:
- Cars B and C are exceeding the speed limit and will receive speeding tickets.
