You can put this solution on YOUR website! The earth has a 4000 mile radius and rotates one revolution every 24 hours. What is the linear speed of a point on the equator, in miles per hour.
**
circumference of earth at equator=2πr=2π*4000=8000π miles
linear speed of a point on the equator=8000π mi/24hrs≈1047 mi/hr
