Have you any ideas on what method to use?
Start by drawing a picture of the scenario described.
A plane's air speed is 520 mi/hr. Find the bearing (theta) the plane should fly to get to Seattle and the new speed (r) when the wind is blowing from a bearing of 120degrees with a speed of 120 mi/hr. The bearing from Hawaii to Seattle is 50 degrees and the distance is 2677 mi. Find the time it takes to fly to Seattle with the new plane speed.
Hello, hubbabubba590!
I have a question . . .
A plane's air speed is 520 mph.
Find the bearing (theta) the plane should fly to get to Seattle and the new speed (r)
when the wind is blowing from a bearing of 120 degrees with a speed of 120 mph.
The bearing from Hawaii to Seattle is 50 degrees and the distance is 2677 miles.
Find the time it takes to fly to Seattle with the new plane speed.
What "new speed"?
With the given data, we have a 'normal' bearing problem.
The plane flies from to at 520 mph.Code:| S| 120d N * | * * | * 110d * | 2677 * * | * * A | * * | * * |50d* * | * * H *
The wind blows from to at 120 mph.
We can find the bearing and the distance
What purpose does the "new speed" serve?
Perhaps it's because the speed and direction of the wind causes the plane to slow down? I'm not quite sure, it's a practice problem my trigonometry teacher gave us. We are currently studying the applications of vectors in the plane.
