A wind is blowing directly from east to west. The pilot of a small plane finds that if he points the nose of the plane 30.0 ° north of east, his velocity with respect to the ground is in the direction 55.1 ° north of east. The speed of the plane with respect to the air is 126 ...

A plane travelling at a speed of 150 meter per second due east of north has to go from point A to point B 500 km apart. If a wind blows straight north at a speed of 20 meter per second find the angle the pilot should follow to reach point B and also the time taken in flying ...

**math**

It took a small plan 1 hour longer to fly 480 miles against the wind than it took the plane to fly the same distance with the wind. If the wind speed was 20 mph, then what is the speed of the plane in calm air?

**Physics**

A small aircraft has a flying speed of 200 km/h in still air. To make a trip from Saskatoon to Regina, a straight line distance on the map of 250 km, a pilot must first determine the wind velocity and then calculate what direction to fly (the 'heading') to compensate for the ...
