You can put this solution on YOUR website!
$\"d=rt\"$ Start with the distance-rate-time formula\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"d=55t\"$ Plug in $\"r=55\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in \"t\" hours, the car will travel $\"55t\"$ miles. For instance, if $\"t=2\"$ , then $\"55t=55%282%29=110\"$ which means in 2 hours the car travels 110 miles.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the algebraic expression for the distance is $\"55t\"$ where $\"55\"$ is the coefficient (in this case there is no constant) and $\"t\"$ is the variable\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
