A man stands on the roof of a 19.0 m tall building and throws a rock with a velocity of magnitude 30.0 m/s at an angle of 30.0 degrees above the horizontal. Ignore air resistance. Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground.

105 meters
find seconds to reach maximum height which is 1.53 s. Then find time it takes for object to drop 30.5 meters, 2.49 seconds. Add them together then multiply by initial x velocity and you get 105 meters. 
Dude not everyone knows F***** physics explain your process.
