What unit can a sedan travel 70 per hour?

[GriffinLynn]

A sedan can travel 70 kilometers per hour, and the distance it travels per hour is called speed, which can be written as 70 km/h. Definition of speed: It can be understood that the distance traveled per hour is called speed; then, according to the representation method of speed, it is separated by a slash, with the distance traveled per unit time written on the left side of the slash and the time unit written on the right side. Based on this, the speed of the car can be written and read out. Method for judging speed: The distance from the car in front is determined by visually estimating the area of the front part of the vehicle blocking the rear part of the car in front. Different car models have different front views, so the standards for judging the distance from the car in front vary depending on the car model. It needs to be determined according to the actual situation of your own vehicle, but the judgment method is consistent.
