\n" ); document.write( "A plane can fly 280 miles in the same time as it takes a car to go 100 miles. If the car travels 90 mph slower than the plane, find the speed of the plane.
\n" ); document.write( "
Let speed of plane be S
\n" );
document.write( "Then speed of car  = S - 90
\n" );
document.write( "We then get the following TIME equation: \"matrix%281%2C3%2C+280%2FS%2C+%22=%22%2C+100%2F%28S+-+90%29%29\"
\n" );
document.write( "Cross-multiply to get: 280(S - 90) = 100S
\n" );
document.write( "Continue to solve for S, and you should get:  \n" );
document.write( "
\n" );
