A jogger begins her workout by jogging 7 miles to the park.
\n" ); document.write( " She takes an alternate route home that takes an hour longer and is a total of 14 miles.
\n" ); document.write( " If she jogs at the same pace what is her speed?
\n" ); document.write( ":
\n" ); document.write( "let s = the jogging speed
\n" ); document.write( ":
\n" ); document.write( "Write a time equation; time = dist/speed
\n" ); document.write( "14 mi time - 7 mi time = 1 hr
\n" ); document.write( " $\"14%2Fs\"$ - $\"7%2Fs\"$ = 1
\n" ); document.write( "multiply equation by s
\n" ); document.write( "14 - 7 = 1s
\n" ); document.write( "s = 7 mph is her speed
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Confirm this find the actual time each way
\n" ); document.write( "14/7 = 2 hrs
\n" ); document.write( "7/7 = 1 hr
\n" ); document.write( "----------------
\n" ); document.write( "dif: 1 hr \n" ); document.write( "

\n" );
