Ответ:
the airplane is 130.56 km south of the airport after 2 hours
Step-by-step explanation:
given data
travel speed = 120
time travel = 2 hour
direction = 260°
solution
we get here direst distance covered by plane in 2 hours that is
distance cover = 120 × 2
distance cover = 240 kilometers
and
the south component of the distance will be here as
distance = 240 × sin(270 - 260) = - 130.56
so the airplane is 130.56 km south of the airport after 2 hours
