**Reiny**, Monday, October 15, 2012 at 10:41pmspeed of passenger ---- x mph

speed of jet -----------2x mph

they each went for 4 hours, so

distance covered by jet = 4(2x) = 8x

distance covered by pass = 4x

8x + 4x = 2400

12x = 2400

x = 200

passenger plane went 200 mph, and the jet went 400 mph

Just noticed that I answered the same question back in Nov of 2007
