You just have to substitute values of slope and vertical distance in formula and get value of horizontal distance. Similarly, any one of them can be found if other two are given. For instance, if you have a slope given in Percentage as 10 % and a vertical distance of 50 feet, then equation will look like:
Furthermore, since there is no horizontal acceleration, the horizontal distance traveled by the projectile each second is a constant value - the projectile travels a horizontal distance of 20 meters each second. This is consistent with the initial horizontal velocity of 20 m/s. Thus, the horizontal displacement is 20 m at 1 second, 40 meters at 2 seconds, 60 meters at 3 seconds, etc. This information is summarized in the table below.
