let s = Rico's bicycle's speed
\n" ); document.write( "\"Pedro can drive 4 times as fast as Rico can ride his bicycle.\"
\n" ); document.write( "therefore
\n" ); document.write( "4s = Pedro's speed
\n" ); document.write( ":
\n" ); document.write( " If it takes Rico 3 hours longer than Pedro to travel 76 miles, how fast can Rico ride his bicycle?
\n" ); document.write( "Write a time equation, time = dist/speed
\n" ); document.write( "R's time - P's time = 3 hrs
\n" ); document.write( " $\"76%2Fs\"$ - $\"76%2F%284s%29\"$ = 3
\n" ); document.write( "multiply eq by 4s, cancel the denominators
\n" ); document.write( "4(76) - 76 = 3(4s)
\n" ); document.write( "304 - 76 = 12s
\n" ); document.write( "228 = 12s
\n" ); document.write( "s = 228/12
\n" ); document.write( "s = 19 mph is Rico's speed on his bike
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, P's speed: 4 * 19 = 76 mph
\n" ); document.write( "76/19 = 4 hrs
\n" ); document.write( "76/76 = 1 hrs
\n" ); document.write( "------------
\n" ); document.write( "differ: 3 hrs \n" ); document.write( "

\n" );
