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.
\n" ); document.write( "**
\n" ); document.write( "circumference of earth at equator=2πr=2π*4000=8000π miles
\n" ); document.write( "linear speed of a point on the equator=8000π mi/24hrs≈1047 mi/hr \n" ); document.write( "

\n" );
