(a) A pilot wishes to fly from San Francisco to Sacramento 138 kilometer northeast. The wind is blowing from north at 24 km/h, and the plane has airspeed of 240 km/h. Determine what heading must the pilot take, and how long will it take to get to Sacramento?
(b) Determine how long does it take the pilot to get to San Francisco? Compare the round-trip time with the time required with no wind.
