Two jets are traveling toward each other and are 4000km apart. The rate of one jet is 100km/hr faster than the rate of the other. If the jets pass each other after 2.5 hours, what is the rate of each jet?
\n" ); document.write( "---
\n" ); document.write( "closing speed for the two jets is x + x+100 = 2x+100 km/h
\n" ); document.write( "------------
\n" ); document.write( "Equation:
\n" ); document.write( "time = distance/rate = 4000/(2x+100) hrs = 2.5 hrs
\n" ); document.write( "---\r
\n" ); document.write( "\n" ); document.write( "2000/(x+50) = 2.5
\n" ); document.write( "2.5x + 125 = 2000
\n" ); document.write( "2.5x = 1875
\n" ); document.write( "---
\n" ); document.write( "x = 750 km/h (speed of the slower jet)
\n" ); document.write( "x+100 = 850 km/h (speed of the faster jet)
\n" ); document.write( "=============================================
