Answer:
7853.98 miles per hour
Explanation:
Data provided in the question:
Distance of the GPS satellite from the center of the earth, r = 15,000 miles
Time taken to circle around the Earth = 12 hours
Now,
The total distance covered by the satellite while it circles around the Earth
= 2πr
= 2 × π × 15,000
= 94247.78 miles
Therefore,
The speed of travel of satellite = Distance covered ÷ Time taken
= 94247.78 ÷ 12
= 7853.98 miles per hour
