An airplane maintains a speed of 675 km/h relative to the air it is flying through as it makes a trip to a city n2 km away to the north. (Asume north is the positive y direction and eat is the positive rdirection.) (a) what time interval is required for the trip if the plane flies through a headwind blowing at 31E Km/h toward the south? (b) what tiene interval is required it there is a talwind with the same speed? () What time interval is required it there is a crosswind blowing at 31 km/h to the east relative to the ground
