An American press release describing the 1986 nonstop, round-the-world trip by
the ultra-lightweight aircraft Voyager included the following data: flight
distance: \(25,012 \mathrm{mi}\) flight time: 9 days, 3 minutes, 44 seconds fuel
capacity: nearly 9000 lb fuel remaining at end of flight: \(14 \mathrm{gal}\)
To the maximum number of significant figures permitted, calculate
(a) the average speed of the aircraft in kilometers per hour
(b) the fuel consumption in kilometers per kilogram of fuel (assume a density
of \(0.70 \mathrm{g} / \mathrm{mL}\) for the fuel)
