Your question: Two jets leave Dever at 9:00am one flying east at a speed 50 mph greater than the other,which is flying west. At 11:00 am the planes are 2500 miles apart. Find each of their speeds and distances. \n" ); document.write( "---------------------------------------------------------------------------- \n" ); document.write( "Lets define a variable first. \n" ); document.write( "we will say that x is equal to the mph of the slower plane \n" ); document.write( "since the faster plane was going 50 mph faster than the slower plane, x+50 \n" ); document.write( "In all, it took two hours to travel 2500 miles\r \n" ); document.write( "\n" ); document.write( "So the equation would look like this: \n" ); document.write( "2(x)+2(x+50)=2500------solve for x \n" ); document.write( "2x+2x+100=2500-------combine and subtract 100 \n" ); document.write( "4x=2400------divide by 4 \n" ); document.write( "x=600 \n" ); document.write( "so the slower plane is going 600mph \n" ); document.write( "Since the faster plane's equation is x+50, the faster plane is going 650mph! \n" ); document.write( " |
