Hi,
\n" ); document.write( "rate * time = Distance
\n" ); document.write( "Let r be the rate
\n" ); document.write( ".
\n" ); document.write( "The Question states the following to be true:
\n" ); document.write( "r* 5hr = 275
\n" ); document.write( ".
\n" ); document.write( " $\"r+=+55+%28mi%2Fhr%29\"$
\n" ); document.write( ".
\n" ); document.write( "Knowing the rate (or speed) is $\"55+%28mi%2Fhr%29\"$
\n" ); document.write( "The Distance traveled in 7 hrs would be:
\n" ); document.write( ".
\n" ); document.write( " $\"55+%28mi%2Fhr%29%2A7hr+=+highlight%28385+mi%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
