Final answer:
The speed limit of 80 km/h converts to 22.2 m/s and 49.7 mi/h, which is below the typical highway speed limit and much lower than world land speed records.
Step-by-step explanation:
The question relates to converting a highway speed limit from kilometers per hour (km/h) to both meters per second (m/s) and miles per hour (mi/h). The speed limit in question is roughly 80 km/h. To convert this to meters per second, we use the conversion factor where 1 km/h is equal to ≈ 0.2778 m/s. Therefore, 80 km/h is equivalent to 80 × 0.2778 m/s, which equals 22.2 m/s. Now, to convert 80 km/h to miles per hour, we use the conversion factor where 1 km is about 0.6214 miles. Thus, 80 km/h is equivalent to 80 × 0.6214 mi/h, which is approximately 49.7 mi/h.
Additionally, comparing these speeds to typical highway speed limits (60 mi/h or 27 m/s or 96 km/h), we find that 80 km/h is less than the common limit. Also, the typical highway speed limit is smaller compared to the land speed records mentioned.
