The world record established dell'aerostato dell'orbita of 3 Breitling in 1999 traveling 40 814 kilometers in 19 d 21 h 47 min. on 1 March 1999, the balloon had removed from a village in the Swiss Alps. Finally he landed in Egypt on March 21. calculate the average speed dell'aerostato. b) using the average speed that you have calculated that time took the balloon to cross the Atlantic Ocean, a distance of 6670 kilometers? c) in the final round - the world-trip, the balloon flew for 18 h at an average speed of 210 km / hour has traveled far?

Total time in hours = 19*24 + 21 + 47/60 = 477.85
a. Mean speed = 40814/477.85 = 85.412 km/hr (to 5 sig figs)
b. 6670 km * hr/85.412 km = 78.092 hr (to 5 sig figs)
c. 18 hr * 210 km/hr = 3780 km (to 3 sig figs)

first you have to figure out the average speed… do you know that formula? Speed=distance/time…? so it was going 85.5 hm/hour. get it? B) take that speed… and how long did it take to cross the ocean - the formula would be the length of the ocean covered / the speed…. and C) you need to multiply and you need to find it yourself. :)? good?
