Final answer:
The conversion of 80 km/h translates to 22.2 m/s and approximately 49.7 mi/h. The exact maximum speed limit for buses on non-interstate or non-state highways is not provided and typically varies by local traffic laws.
Step-by-step explanation:
The question relates to the conversion of speed limits from one set of units to another, specifically from kilometers per hour (km/h) to meters per second (m/s) and to miles per hour (mi/h). When converting 80 km/h to m/s, we use the conversion factor where 1 km/h is equivalent to 0.27778 m/s. Therefore, 80 km/h is equal to 22.2 m/s. To convert 80 km/h to mi/h, we use the conversion factor where 1 km is approximately 0.621371 miles. This means that 80 km/h is approximately 49.7 mi/h. Accordingly, the correct answer from the provided information is option b. 22.2 m/s, 49.7 mi/h.
Regarding the maximum speed limit for buses on roads that are not interstates or state highways, that information typically varies by jurisdiction and is not stated clearly in this question. Therefore, I cannot provide the exact speed limit without more context or specific local traffic law references. Generally, these limits are set after considering various factors, such as road conditions, traffic flow, and safety regulations, and are often indicated by posted speed signs.
