An airplane flies directly west at 1,000 kilometers per hour. Without changing directions, the plane returns to its starting point in just one hour. What can you infer about the planes route with regard to lines of latitude and longitude? Explain please.

can i get a better hint

The plane is near one of the Poles.

Study a globe. Where can a plane travel only west for an hour and arrive back at its starting place?

Im getting the south pole

It could be either the South or North Pole.

is that the answer?

Yes.

thank you

You're welcome. I hope you looked a globe and have learned how North and South Poles are the answers.

Yes
