Why not just increase the speed? All Actions have this.
Example from our Programmers Guide:
auto mySprite = Sprite::create("mysprite.png");
// Move a sprite to a specific location over 2 seconds.
auto moveTo = MoveTo::create(2, Vec2(50, 0));
// Move a sprite 50 pixels to the right, and 0 pixels to the top over 2 seconds.
auto moveBy = MoveBy::create(2, Vec2(50, 0));
