My bike reached a speed of 36 miles per hour.
\n" ); document.write( " My bike tires have a radius of 14 inches.
\n" ); document.write( "Find the circumference of the tire
\n" ); document.write( "C = \"2%2Api%2A14\"
\n" ); document.write( "C = 87.9646 inches
\n" ); document.write( ":
\n" ); document.write( "If I maintained this speed for 30 seconds, how many revolutions did my bike tire make?
\n" ); document.write( "there are 120 30 sec periods in an hour
\n" ); document.write( "Find the no. of inches traveled in 1 hr at 36 mph, divide by the period and the circumference
\n" ); document.write( "R = \"%2836%2A5280%2A12%29%2F%28120%2A87.9646%29\"
\n" ); document.write( "R = 216.1 rev
