🔍 Key Concepts

• One minute of latitude equals one nautical mile on the Earth’s surface • There are 60 minutes in one degree of latitude • Use unit conversions step by step rather than trying to jump directly to the final number

💭 Think About

• How many nautical miles are in one degree of latitude? • Once you know miles per degree, how many miles would there be in 15 degrees? • Can you write this as a simple multiplication problem using miles per degree × number of degrees?

✅ Before You Answer

• Be sure you are using minutes of latitude, not minutes of time • Confirm you are calculating in nautical miles, not statute (land) miles • Double-check your multiplication of miles per degree × 15° before choosing an option
