Ajet leaves a runway whose bearing is n 3232degrees°e from the control tower. after flying 77 miles, the jet turns 90degrees° and flies on a bearing of s 5858degrees°e for 88 miles. at that time, what is the bearing of the jet from the control tower?

Explanation:

Bearing from control tower=

But

Therefore, the bearing from control tower=

Bearing=

The direction is North East

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
