Distance Speed Time Calculator

OK, I know this is physics and not pure math, but it's free and it might show handy. :-)

This calculator basically does something very simple - it calculates distance, speed (velocity) or time if you have the other two.

If you want to know a little more about this - scroll below the calculator.

It all starts with this formula:

Speed =	Distance
	Time

That's the formula when we have time and distance and want to know the speed (velocity).

---

If we have speed and time, and want to know the distance:

Distance = Speed × Time

---

And finally, if we have speed and distance, and want to calculate the time:

Time =	Distance
	Speed
