The speed of sound in air on a certain stormy day is about 1125 feet per second.
\n" ); document.write( "What is the speed of sound measured in miles per second? Round your answer to four decimal places.
\n" ); document.write( ":
\n" ); document.write( "5280 ft in one mile, therefore
\n" ); document.write( "\"1125%2F5280\" = .2131 mi/sec
\n" ); document.write( ":
\n" ); document.write( "What is the speed of sound measured in miles per hour? Round your answer to the nearest whole number.
\n" ); document.write( ":
\n" ); document.write( "3600 sec in 1 hrs
\n" ); document.write( "\"%28%283600%2A1125%29%29%2F5280\" = 767 mph
