Thanks, I am having a little trouble...

1.A ship is travelling @ 12 m/s. A passenger walks towards the back at 5 m/s. After walking for 2 sec, he then walks at the same speed at right angles to the direction of the ship for 2 secs.

Relative to the water:

a. What is the velocity in each case

b. What is the displacement in each case

2.A ship travelling @ 46km/hr aiming at the direction 124 T is pulled off course by a current of 8 km/hr in the direction 223 T. Find actual speed and direction of ship.

THanks for the help!
