Bonus A jet is flying from Hawaii to San Francisco, a distance
of 2400 miles. In still air, the jet flies at 600 mph, but there
is now a 40-mph tailwind. In case of emergency, how many
hours after takeoff will it be faster for the jet to go on to
San Francisco rather than to return to Hawaii?
B: more than 1.75h
