Which parameter of a projectile depends on the horizontal as well as the vertical component of velocity of projection?

Just about anything you could ask about a projectile AFTER it's launched
depends on both components of the launch velocity. 

Here are some that I can think of:

-- angle of launch
-- magnitude of launch velocity
-- location at any time after launch
-- magnitude of velocity at any time after launch
-- direction of velocity at any time after launch
-- distance of the landing point from the launch point

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second
