How Fast is 25km/h?

[DeJustin]

In everyday language, the term 'speed in code' originates from the speed unit 'mile'. The commonly mentioned speed of 100 code is equivalent to 100 kilometers per hour, while the British term '100 miles' equals 160 kilometers per hour. Therefore, 25km/h represents 25 miles, whereas in foreign countries it is 40 miles, which is approximately a speed of 7 meters per second. Relevant information about speed limits is as follows: 1. Introduction to Speed Limits: Speed limits usually refer to the regulation of vehicle speeds within a certain numerical range over a specific length of road. 2. Purpose of Speed Limits: The main purpose is to pre-warn drivers to reasonably control their speed in subsequent road sections ahead, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and also the most important part of road transport safety.

25 kilometers per hour is roughly the speed you'd achieve by pedaling a shared bike with a bit of effort—faster than walking but far from lightning speed. I usually maintain this pace when driving my family car around the neighborhood, allowing me to notice details like shop signs on the roadside and stop in time if a stray cat crosses my path. Converted to running, it's equivalent to the pace of a national team middle-distance runner. For an average person, completing a 400-meter lap on a track at this speed is already considered quite fast. In daily life, delivery riders on electric tricycles and elementary students biking to school often hover around this speed.

To put it in terms of a sports stadium, 25 mph is equivalent to completing a full lap around a 400-meter standard track, including the turns, in just one minute. When I was losing weight last year, I specifically measured it—running at a pace of 6 minutes per kilometer, covering 1 kilometer took exactly 6 minutes, which translates to a speed of 10 km/h. 25 mph is one and a half times faster than a brisk run, a speed that ordinary people simply can't achieve on flat ground. When a car is slowly moving forward in first gear or when an electric vehicle just starts to accelerate, the needle on the dashboard hovers around this position.

The cruising speed right after a car exits the underground garage. Experienced drivers know that at this point, you just lightly tap the accelerator—it's even too early to shift into second gear. Maintaining this speed during turns eliminates the need for deliberate braking, and it allows enough reaction time for sudden appearances of delivery e-bikes. This speed range is what novice drivers should practice mastering the most—it neither crawls too slowly to block traffic nor fails to stop steadily before crosswalks when encountering pedestrians crossing.
