two planes start from the same point, and fly in opostie directions, the first Plane is flying 25mph slower than the second plain. In two hours the planes are 470 miles apart. Find the rate of speed of each plane.
\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "let x=speed of first plane
\n" ); document.write( "then x-25=speed of slower plane
\n" ); document.write( "distance=speed*travel time
\n" ); document.write( "Travel time for both planes=2 hours
\n" ); document.write( "Since they fly in opposite directions,
\n" ); document.write( "2x+2(x-25)=470
\n" ); document.write( "2x+2x-50=470
\n" ); document.write( "4x=470+50
\n" ); document.write( "4x=520
\n" ); document.write( "x=130 mph
\n" ); document.write( "x-25=105 mph
\n" ); document.write( "ans:
\n" ); document.write( "Speed of the first plane = 130 mph
\n" ); document.write( "Speed of the second plane = 105 mph\r
