🔍 Key Concepts

• Great circle definition on a sphere (shortest distance between two points) • Approximate circumference of the Earth at the equator in nautical miles and in statute miles • Relationship between 360° of a circle and total distance around the Earth

💭 Think About

• First, recall roughly how many miles it is all the way around the Earth at the equator. Which choice is closest to that full circumference? • Think about how many miles correspond to 1° of latitude, then multiply by 360°. Does that product match any of the options? • Check whether the answer should be in tens of thousands of miles or just a few thousand. Does a full circle around Earth sound more like an ocean crossing or just a short regional voyage?

✅ Before You Answer

• Verify the commonly used value for Earth’s circumference in statute miles (not nautical miles) • Confirm how many degrees are in a full circle (great circle) and how many miles per degree are typically used • Eliminate any options that are clearly too small to represent the entire distance around the globe
