Tofind:How far east will the plane have travelled from its point of departure.
Answer to Problem 35E
The plane is flying 709 miles east after 1.5 hours.
Explanation of Solution
Given:
the bearing of plane is
Plane is at speed of 600 MPH at time 1.5 hours.
Concept used:
Speed
Trigonometric ratio:
Calculation:
Since, the bearing of plane is
Let the vertical height travelled by plane from base in time 1.5 hours be h.
Distance travelled by plane at speed of 600 MPH at time 1.5 hours is given by
Speed
Now by considering right
Therefore, the plane is flying 554miles north after 1.5 hours.
Let the horizontal distance travelled by the plane in 1.5 hours be l.
Again, in right
Therefore the plane is flying 709 miles east after 1.5 hours.
