What does a car traveling at 80 per hour mean?

[AylaLee]

A car travels at 80 km (kilometers) per hour. Here is an introduction to car speed: 1. On urban expressways: It takes about 1 hour for a car to travel 80 kilometers, which means it travels at 80 km/h. Most cars today can reach a speed of 80 km/h. The car's speed is 80 km/h, which can also be written as 80 KM/H, meaning it can travel 80 kilometers per hour at this speed. 2. On highways: The maximum speed limit on domestic highways is 120 km/h, with some sections even lower. This means the maximum speed for small passenger vehicles must not exceed 120 km/h, and drivers must adhere to the posted speed limits and markings in designated sections.
