Earth's diameter

The Earth's diameter on the equator is approximately 12750 km. How long does the Gripen fly over the Earth above the equator at 10 km if it is at an average speed of 1500 km/h?

Correct answer:

t =  26.7454 h

Step-by-step explanation:

D=12750 km a=10 km o=π (D+2 a)=3.1416 (12750+2 10)40118.1382 km v=1500 km/h t=o/v=40118.1382/1500=26.7454 h
