The instruments with an aircraft show that it is headed east with an airspeed of 180 mph. After 2 hours, the aircraft is actually 375 miles east and 20 miles north of its starting point. Find the wind speed and its direction.

Answer 1

the plane flew 360 mi east in the air

but the air moved east and north
... this is the wind speed

15 mi E and 20 mi N forms a 3-4-5 triangle

the wind is ... 25 mi / 2 hr
... on a bearing N of E

the tangent of the bearing angle is
... 20 / 15
