How it's used
While 速率 is the technically correct term for rate or speed in scientific contexts, it is rarely used in casual daily conversation. Most people prefer using 快慢 or 速度 to describe how fast something is moving or happening. Using 速率 in a casual setting can make you sound like you are reading from a textbook or giving a formal presentation.
Examples

Common mistake
Do not confuse 速率 with 速度. In physics, 速度 is a vector that includes direction, whereas 速率 is a scalar representing only magnitude. In everyday speech, people use 速度 for almost everything, so using 速率 might sound overly pedantic.
