Two boys on bicycles start toward each other at the same time from two towns 70km
\n" ); document.write( " apart. The first travels at 12km/h. What is the speed of the other boy if they
\n" ); document.write( " meet in 2 1/2 hours?
\n" ); document.write( ":
\n" ); document.write( "Let s = speed of the other boy
\n" ); document.write( ":
\n" ); document.write( "When they meet they will have traveled a total of 70 km
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation: Dist = time * speed
\n" ); document.write( ":
\n" ); document.write( "1st boy dist + 2nd boy dist = 70 km
\n" ); document.write( "2.5(12) + 2.5s = 70
\n" ); document.write( "30 + 2.5s = 70
\n" ); document.write( "2.5s = 70 - 30
\n" ); document.write( "s = $\"40%2F2.5\"$
\n" ); document.write( "s = 16 mph speed of the other boy
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the total dist
\n" ); document.write( "30 + 2.5(16) = 70 \n" ); document.write( "

\n" );
