Put the start of the ramp at a height z=h and the end of the ramp at z=0. Now you can use energy conservation to determine the height. Knowing the height and angle of a right-angled triangle allows you to calculate the distance.

Put the start of the ramp...
The OP needs to show some effort in order to help with solving.

I think the mass of the skier should be given to find the acceleration and solve.
