You can put this solution on YOUR website!
you must pay attention to your units and make sure you interpret what the rate is as opposed to the distance and time.
\n" ); document.write( ":
\n" ); document.write( "the rate is not 25 minutes..... the rate is 1mi/25min
\n" ); document.write( ":\r
\n" ); document.write( "\n" ); document.write( "so 7mi=(1/25)(mi/min)(t)
\n" ); document.write( ":
\n" ); document.write( "t=7mi(25/1 (min/mi))...see how the units cancel each other so that we end up with 175 min.
\n" ); document.write( ":
\n" ); document.write( "the way you were doing it you ended up with $\"%28mi%29%5E2%2Fmin\"$ \n" ); document.write( "

\n" );
