Question 78302: A plane took 1 hour longer to travel 560 miles on the first portion of a flight than it took to fly 480 miles on the second portion. If the speed was the same for each portion, what was the flying time for the second part of the trip?
thanks

You can put this solution on YOUR website! If the plane travels at the same speed for both flights, and the plane took 1 hour longer for the first portion, then all you have to do is subtract how long it traveled on the first portion then the second portion. That is how far it traveled in the extra hour. To figure out the flying time, do distance / speed. 560 - 480 = 80. THe plane travels at 80 miles every 1 hour, or 80mph. Now that you know this, do 480/80. Your answer will be 480/80 hours, or 6 hours.
6 is the answer to your problem. YOU ARE WELCOME!
