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.

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.
