6) A human-powered airplane, the Gossamer Albatross, flew from England, to France. It covered a straight-line distance of 38.5 km in 2 h 49 min. What was its average speed?

BIO Human-Powered Flight Human-powered aircraft require apilotto
pedal, as in a bicycle, and produce a sustained power outputofabout 0.30 hp. The Gossamer Albatross flew across theEnglishChannel on June 12, 1979, in 2h 49 min. (a) How much energydid thepilot expend during the flight? (b) How many Snickers candybars(280 Cal per bar) would the pilot have to consume to be“fueledup” for the flight? [Note: The nutritionalcalorie, 1Cal, isequivalent to 1000 calories (1000 cal) as definedin physics. Inaddition, the conversion factor between calories andjoules is asfollows:
1Cal = 1000 cal = 1 kcal = 4186 J. ]

Human-powered aircraft require a pilot to pedal, as in a bicycle,and produce a sustained power output of about 0.290 hp. TheGossamer Albatross flew across the English Channel on June 12, 1979in 2 h 49 min.
(a) How much energy would the pilot expend on a flight lasting 164min?
(b) How many Snickers candy bars (280 Cal per bar) would the pilothave to consume to be "fueled up" for the flight?
