Physics: Projectile Motion/Relative Motion

A group of people on vacation on a cruise ship decide to go up to the top floor. Some decide to take an elevator, which moves at 2m/s, while others climb the stairs at 2m/s. The stairs are at an angle of elevation of 38 degrees up from the east direction. The boat cruising at a velocity of 3.2 m/s east relative to the water.
(A) calculate the velocity of the people in the elevator relative to the water.
(B) calculate the velocity of the people taking the stairs relative to the water.

Please show steps thanks!
