George v coast in Antarctica is the windiest place on earth. Wind speeds there can reach 3.00 x 10^{2} km/h. if a research plane flies against the wind with a speed of 4.5 x 10^{2} km/h relative to the wind, how long does it take the plane to fly between two research stations that are 250 km apart?

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

Can anybody me with this? ? (picture included.)
