    Did you have some specific problem in mind?

    Average speed, by definition, equals distance/time.
  4. 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.
  6. 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.
  8. I got it... Thanks!
