document.write( "Question 1124835: A manager travels 2000 miles in a jet and then an additional 500 miles by car. If the car takes one hour longer than the jet ride, and if the speed of the jet is 5 times that of the car, find the time the manager travels by jet and by car, respectively. \n" ); document.write( "
