Understanding 时速
The term 时速 (shísù) specifically refers to speed measured in distance per hour, commonly kilometers per hour (km/h). It is used to describe how fast something moves over time, such as vehicles or airplanes.
Usage in Conversation
时速 is often used when discussing transportation, traffic regulations, or comparing speeds. For example, you might hear it when talking about a car's speed or speed limits on roads.
Common Collocations
- 时速达到 (shísù dádào): to reach a certain speed
- 最高时速 (zuìgāo shísù): maximum speed limit
- 时速限制 (shísù xiànzhì): speed restriction
These collocations help specify the context of speed, whether it's about limits or actual measured speed.
Tips
时速 is a technical term and is usually paired with numbers or units like 公里 (kilometers). Avoid confusing it with 速度 (sùdù), which is a more general term for speed and can be used in broader contexts beyond hourly measurement.
