A plane flies 1.3 hr at 100mph on a bearing of N40degreesE. It then turns and flies 1.5hr at the same speed on a bearing of S50degreesE. How far is the plane from its starting point?

Answer 1

130 at 60 deg up from x axis
150 at 40 deg down from x axis

x component = 130 cos 60 + 150 cos 40
y component = 130 sin 60 - 150 sin 40

magnitude = sqrt (x^2+y^2)
