2. [-11 Points] DETAILS SERPSE10 4.6.0P.026. MY NOTES A plane is flying to a city 716 km directly north of its initial location. The plane maintains a speed of 163 km/h relative to the air during its flight. (a) If the plane ies through a constant headwind blowing south at 53.5 km/h, how much time (in h) will it take to reach the city? |:|h (b) If instead the plane flies through a constant tailwind blowing at 53.5 km/h, how much time (in h) will it take to reach the city? |:lh (c) If instead the plane flies through a constant crosswind blowing east at 53.5 km/h, how much time (in h) will it take to reach the city? |:lh Need Help? 3. [-11 Points] DETAILS SERPSE10 4.6.P.026. MY NOTES The pilot of an airplane notes that the compass indicates a heading due west. The airplane's speed relative to the air is 140 km/h. The air is moving in a wind at 28.0 km/h toward the north. Find the velocity of the airplane relative to the ground. Magnitude km/h Direction north of west Need Help? 4.
