Use the formula distance=rate x time
\n" ); document.write( "the distance travelled is 54.8 miles
\n" ); document.write( "the time is 4 hours
\n" ); document.write( "we want to solve for the rate, how many miles per hour
\n" ); document.write( "let r=rate\r
\n" ); document.write( "\n" ); document.write( "54.8=r(4)
\n" ); document.write( "divide both sides by 4 to get the variable r by itself
\n" ); document.write( "r=13.7
\n" ); document.write( "the cyclist travels 13.7 miles per hour\r
\n" ); document.write( "\n" ); document.write( "but the question asks how far can the cyclist travel in 5 hours
\n" ); document.write( "using the same formula again
\n" ); document.write( "distance=rate x time
\n" ); document.write( "the distance is what we are looking for this time
\n" ); document.write( "let d=distance
\n" ); document.write( "we know the rate is 13.7 miles per hour
\n" ); document.write( "we know the time is 5 hours
\n" ); document.write( "d=13.7(5)
\n" ); document.write( "d=68.5\r
\n" ); document.write( "\n" ); document.write( "answer: the cyclist can travel 68.5 miles in 5 hours\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
