The projectile lands 165 m far.

Explanation:

First of all you have to find the time when the projectile land, so vt-1/2at^2=0, so t=3s. For this equation you consider the vertical component of speed v(y)=vsin15°.
Now you have the time's value and can use it in the orizontal equation s=vt, where v=vcos15°.
s=55m/s*3s=165m.
