Speed = Distance/Time

Who discovered this?

Someone online said Galileo. I thought it must have been the ancients.

Google says Galileo.

I'm still sceptical.

Re: Speed = Distance/Time

distance and time are defined as fundamental units https://en.wikiversity.org/wiki/Fundamental_units

Speed is a derived unit.

The ancients certainly had the concept. Mariners, for example, would throw a piece of wood overboard to estimate the speed of their ship.  And I'm sure many horses were sold taking account of their speed.

Speed is a rate of change (of distance with respect to time) but it doesn't seem like they had the idea of miles per hour (using their own unit for distance).

So maybe Galileo was the first to do this.
