2. A helicopter flies with a velocity of 45 km/h [N 350 E] for 2.8 hours. After doing so, it turns sharply and flies with velocity of 67 km/h [S 650 E]. ] for an additional 3.0 hours. Determine the velocity that it must fly in order to return to its original position in 3.5 hours. = 45 km / h [ N 35 . E] , V z = 67 KM / h [s 65of] , At 6.3 hours beEd 3. 0 2
