186*x=(x-2)*434 868=(434-186)*x x=868/248 hours answer is x hrs after marty left airport.Is the airport moving?? anyway we are saying in3.5hrs marty went 186*3.5 miles in1.5 hrs the other jet go's 186*3.5 MILES =1.5*434 MILES JA DAT'S WHAT SAYING.tHESE ARE INTERESTING 186 mph relative to what? Must be saying 186 miles ,in straight line , away from airport in 1 hour. So in 2 hrs 392 miles away.in 1.5 hrs more (392 +1.5*186) miles away.In 1.5 hrs the other jet is 1.5* 434 miles away if on same straight line he gets hit in rear?? dONT'T FORGET YOUR WATCH!
