Question 78302
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!
