Trig Question: A ship leaves the port of Miami with a bearing of S80E and a speed of 15 knots. After 1 hour, the ship turns 90degrees toward the south. After 2 hours, maintaining the same speed, what is the bearing to the ship from the port?

Answer 1

15 knots per what?
If the ship goes SE and it turns 90 degrees. This is a right triangle. Use a*2+B*2=c*2
If it is 15 knots per hour. Then after 2 hours it travels 30 knots.
Leg1=15
Leg2=30
It has traveled 33.5 knots to the S160.
