Final answer:
The maximum speed limit for vehicles towing trailers on a two-lane undivided highway is 55 mph unless indicated otherwise. An 80 km/h speed limit is roughly equivalent to 22.2 m/s or 49.7 mi/h. A car traveling at 33 m/s is exceeding a 90 km/h speed limit as it is traveling at 118.8 km/h.
Step-by-step explanation:
On a two-lane undivided highway, the maximum speed limit for vehicles towing trailers is 55 mph unless otherwise posted. This rule is generally set for safety reasons, as towing a trailer can significantly affect vehicle handling and stopping distance.
To address a related concept, the speed limit of 80 km/h when converted into meters per second is approximately 22.2 m/s, because 1 km/h is equal to about 0.27778 m/s. To convert km/h to miles per hour, we use the conversion factor that 1 km is approximately equal to 0.621371 miles, making 80 km/h roughly 49.7 mi/h.
For example, if a car is traveling at a speed of 33 m/s, converting this speed into kilometers per hour results in 118.8 km/h (since 1 m/s equals 3.6 km/h). Comparing this with a speed limit of 90 km/h shows that the car is exceeding the speed limit.
