AI Thread Summary
The equation v = d/t represents average speed, where v is speed, d is distance, and t is time. The discussion clarifies that this formula cannot be rearranged to v = d*t, as they are not equivalent. Speed is measured in units like meters per second (m/s), emphasizing the importance of understanding the relationship between distance and time. The use of "/" in mathematical terms is a precise way to express "per," aligning everyday language with mathematical language. Overall, the conversation highlights the fundamental definition and measurement of speed.

Why dose v = d/t ?

Did you have some specific problem in mind?

Average speed, by definition, equals distance/time.
 
so, it could be also: v = d*t ?

No. Those are not equivalent at all.

Think how speed would be measured: meters per second, m/s, for example.
 
why did you replace per with / ... ?

That's what it means. I just translated everyday language into the more precise mathematical language.

If your speed is 60 miles per hour, you can write that as 60 miles/hour.
 
I got it... Thanks!
