\n" ); document.write( "\n" ); document.write( "Comparing travel. A plane can fly 300 miles in the same time as it takes a car to go 120 miles. If the car travels 90 mph slower than the plane, find the speed of the plane?
\n" ); document.write( "


\n" );
document.write( "Let speed of plane be S
\n" );
document.write( "Then speed of car = S – 90
\n" );
document.write( " ----- Both cover respective distances in the same amount of time
\n" );
document.write( "300(S – 90) = 120(S) ------ Cross-multiplying
\n" );
document.write( "300S – 27,000 = 120S
\n" );
document.write( "300S – 120S = 27,000
\n" );
document.write( "180S = 27,000
\n" );
document.write( "S, or speed of plane = , or  mph \n" );
document.write( "

\n" );
