A fishing boat travels from a harbour on a bearing of 140 degree for 60 km to an island how far due east does it travel?
Answered by oobleck
60 cos(90-140)° = 60 cos50° = 38.56 km

Actually, the <u>bearing</u> of the island from the harbour is 140°
The <u>heading</u> of the ship was thus set to 140°
Answered by henry2,
d = 60km[140o] Cw from +y-axis.
X = 60*sin140 = 38.56 km.
