The airplane makes a round trip.
This means that it travels 340km forward in 0.6 hours, then travels 340km backward in 0.6 hours.
The velocity of the airplane for the first part is +157.4m/s.
The velocity for the second part is -157.4m/s.
157.4 - 157.4 = 0
The average velocity is therefor 0m/s.Source(s): Adv. Higher Physics
