it took you 19 minutes and 37 seconds to run 5 kilometer.
\n" ); document.write( " how long did it take you to run each mile?
\n" ); document.write( ":
\n" ); document.write( "Change 19 min 37 sec to seconds: 19(60) + 37 = 1177 seconds
\n" ); document.write( "Change 5 km to miles: .6214 * 5 = 3.107 miles
\n" ); document.write( ":
\n" ); document.write( "let t = time to run a mile
\n" ); document.write( "Write a ratio equation
\n" ); document.write( "\"t%2F1177\" = \"1%2F3.107\"
\n" ); document.write( "3.107t = 1177
\n" ); document.write( "t = 1177/3.107
\n" ); document.write( "t ~ 378.8 seconds which is 6 min 19 sec to run a mile
\n" ); document.write( "
\n" );
