Algebra.Com's Answer #113250 by orca(409) ![]() You can put this solution on YOUR website! Let x be the speed of the slower jet. \n" ); document.write( "Then the speed of the faster one is x + 50. \n" ); document.write( "The distance that separating them at the end of 2 hours can be expressed in terms of x as: \n" ); document.write( "2x + 2(x + 50) \n" ); document.write( "As the separating distance is 2500, we have \n" ); document.write( "2x + 2(x + 50) = 2500 \n" ); document.write( "Solving for x, we have \n" ); document.write( "2x + 2x +100 = 2500 \n" ); document.write( "4x = 2400 \n" ); document.write( "x = 600 \n" ); document.write( "So the speed of the slower jet is 600 miles per hour \n" ); document.write( "the speed of the fast jet is x + 50 = 650 miles per hour. \n" ); document.write( " |
