Question 645671: I am a math tutor now and I'm having a hard time remembering how to swt this up.
Paul and Randy are taking a trip. Paul drives at 85mph. Randy drives at 90mph. Randy drove three hours longer than Paul. All together they covered 970 miles. How long did each person drive. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Paul and Randy are taking a trip.
Paul drives at 85mph. Randy drives at 90mph.
Randy drove three hours longer than Paul.
All together they covered 970 miles. How long did each person drive.
:
Let t = Paul's driving time
then
(t+3) = Randy's driving time
:
Write a dist equation; dist = speed * time
85t + 90(t+3) = 970
