Question
Find the distance along an arc on the surface of Earth that subtends a central angle of 5 minutes $\left(1 \text { minute }=\frac{1}{60} \text { degree }\right) .$ The radius of Earth is $3,960 \mathrm{mi}$.
Step 1
We know that 1 minute is equal to $\frac{1}{60}$ of a degree. Therefore, 5 minutes would be equal to $5 \times \frac{1}{60}$ degrees. Show more…
