Bonnie drove 540 miles in three times the time it took Buffy to travel 135 miles. Buffy's speed was slower than Bonnie's by 15 miles per hour. Find the rate and time of each
\n" ); document.write( "-------------
\n" ); document.write( "Bonnie DATA:
\n" ); document.write( "distance=540 miles ; time= 3x hours; rate= d/t= 540/3x= 180/x mph
\n" ); document.write( "--------
\n" ); document.write( "Buffy DATA:
\n" ); document.write( "distance=135 miles ; time = x hours ; rate = d/t= 135/x mph
\n" ); document.write( "-------------\r
\n" ); document.write( "\n" ); document.write( "EQUATION:
\n" ); document.write( "Buffy rate+15 = Bonnie rate
\n" ); document.write( "135/x + 15 = 180/x
\n" ); document.write( "Multiply thru by x to get:
\n" ); document.write( "135 + 15x = 180
\n" ); document.write( "15x=45
\n" ); document.write( "x=3 hrs (Buffy time); Buffy rate=135/3=45 mph
\n" ); document.write( "Bonnie time= 3x = 9 hrs: Bonnie rate=180=x=180/3=60 mph
