A plane flies 1.4 hours at 150 mph on a bearing of 10. It then turns and flies hours at the same speed on a bearing of . How far is the plane from its starting​ point?

Sagot :

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a [tex]10^{\circ}[/tex] bearing, then flies at the very same speed at [tex]100^{\circ}[/tex] bearings for 8.5 hours.

However an angle of [tex]100-10 = 90^{\circ}[/tex] between displacements

First shifts[tex]= 1.5 \times 120 = 180\ miles.[/tex]

Second shift [tex]= 8.5\times 120 = 1020\ miles.[/tex]

These two shifts are at [tex]90^{\circ}[/tex] and therefore the final shift is:

[tex]\to \sqrt{180^2+1020^2}=1035.76 \ miles[/tex]
