Ok I'm totally confusing myself here and drawing a blank...

If I have change in x and change in y (dx and dy) over a specified amount of time in milliseconds, and I calculate time intervals by (time / dx) and (time / dy), how do

I calculate the distance intervals for each time period?

This is a stupid math question... but I'm seriously just blanking out here...

I think what you're looking for is:

1 2
| distanceintervalx = dx * time period / time distanceintervaly = dy * time period / time |

Example:

**dx = 5m, dy = 10m, dt = 2s**If you want a time period of 1s, then:

**distanceintervalx = 5 * 1 / 2 = 2.5 m/s**

distanceintervaly = 10 * 1 / 2 = 5 m/sThat's what we usually call
