To find the distance the satellite travels in 1 hour, we first need to find the circumference of the circular orbit.
The radius of the Earth + altitude of the satellite = 6400 km + 4700 km = 11,100 km
The circumference of the circular orbit = 2πr = 2π(11,100 km) = 22,200π km
Since the satellite completes one orbit every 5 hours, in 1 hour it travels 1/5 of the circumference:
(1/5) * 22,200π ≈ 13,949 km
Therefore, the satellite travels approximately 13,949 km in 1 hour. The closest option is 13,949 km.
A weather satellite in circular orbit around Earth completes one orbit every 5 hours. The radius of Earth is about 6,400 km and the satellite is positioned 4,700 km above the Earth. How far does the satellite travel in 1 hour? Round your answer to the nearest kilometer. (1 point) Responses 5,906 km 5,906 km 69,743 km 69,743 km 13,949 km 13,949 km 8,042 km
