Speed relates to distance. With a 3/4 hit, not only will the cue ball deflect at 25%, and the object ball at 75% of the contact speed, the object ball will travel 3 feet for every 1 foot traveled by the cue ball.

In the diagram above the cue ball was stroked with a speed that would send it 4 feet. When it hits the object ball (a 3/4 hit) the object ball is sent 3 feet, and the cue ball 1 foot. The distance is equal to the percentage ratio (3 /1 ft. = 75/25%.)

You can test this for yourself. Put an object ball on the head spot. Place the cue ball between the object ball and the head rail so that the inside edge of the cue ball is lined up as shown below. The inside edge of the cue ball is lined up to intersect a point 3/4 the distance from the outside edge of the object ball (25% from the inside edge.) If this is confusing, just set up as shown below.
Stroke the cue softly with a center ball hit. Drive the object ball 3 feet, and then measure the distance the cue ball traveled after the hit. It should be 1 foot.

If you drive the object ball 6 feet with this same set-up, the cue ball should travel 2 feet (6/2=3/1 ratio, or 75/25).
