* Calculate the speed required to cover a given distance in a given time.

*
* @param {number} distance - The distance to travel, in pixels.
* @param {number} time - The time allowed to cover the distance, in seconds.
*
* @return {number} The speed required, in pixels per millisecond.

* Phaser.Math.GetSpeed(400, 1) // -> 0.4
