\n" ); document.write( "\n" ); document.write( "Bob drove 200 miles in the same amount of time that it took a propeller plane to fly 1,100 miles. The speed of the plane was 180 mph faster than the speed of the car. Find the speed of thee car and the speed of the plane.
\n" ); document.write( "

Let speed of car be S
\n" );
document.write( "Then speed of plane = S + 180
\n" );
document.write( "Time car takes to travel 200 miles: 
\n" );
document.write( "Time plane takes to travel 1,100 miles: 
\n" );
document.write( "Since times are equal, we get: 
\n" );
document.write( "1,100S = 200(S + 180) -------- Cross-multiplying
\n" );
document.write( "1,100S = 200S + 36,000 
\n" );
document.write( "1,100S – 200S = 36,000
\n" );
document.write( "900S = 36,000
\n" );
document.write( "S, or speed of car = , or  mph
\n" );
document.write( "Speed of plane: 40 + 180, or  mph \n" );
document.write( "

\n" );
