A weather satellite I'm 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?

To solve this problem you must apply the proccedure shown below:

1. You have that:

- It completes one orbit every 5 hours.

- The radius of earth is about 6,400 km.

- The satellite is positioned 4,700 km above the earth.

2. Then, you must use the following formula:

S=r θ

r=6,400 km+4,700 km

r=11,100 km

3. When you substitute the values, you obtain:

S = (11,100 km x 2 π) / 5

S=13,949 km

The answer is:13,949 km
