Geometric vectors. PLEASE HELP!!

[Aveym]

Haroon has a remote control electric toy boat that can travel at 6 m/s and wants to steer it across a 250 m wide river to his friend's dock. His friend's dock is on the opposite side of the river, 210 m downstream from looking straight across. There is a current of 2.5 m/s.
a) Draw a vector diagram for this situation and determine the heading that the boat should be steered at relative to the closest shoreline.
b) Determine the time it will take to cross the river.
This is what ive done so far, can someone confirm and let me know if its okay? Thankyou!!!

Oh shoot i meant to post a different question, i already solved this one im sorry

this is the question
I can draw the inclined plane but I dont know what to do next. :/

 

[skeeter]

which force represents the braking force necessary to keep the car at rest on the incline?

mg sin theta? Which would be 8283.3 N if I'm correct?
