The first Earth satellite was flying at a speed of 8000 m/s. At that rate, he circled the Earth in 82 minutes. Jet flies at an average speed of 800 km/h. How long would it take to circle the Earth around?

Correct answer:

t =  49.2 h

Step-by-step explanation:

v1=8000/1000 3600=28800 km/h v2=800 km/h t1=82/60=30411.3667 h t=v1/v2 t1=28800/800 1.3667=5246=49.2=49.2 h  s1 = s2 s1=v1 t1=28800 1.3667=39360 km t2=s1/v2=39360/800=5246=49.2 h
