math,help

Also, can someone set this problem up into equations so i can solve.thanks

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?

One way (v in miles per hour)

Using distance/speed=time

(560/v)+ 1=480/v

find v

then find 480/v for time taken for second part of trip.

I THOUGHT IT WAS

R = D/T

Yes, velocity =distance/time

so time = distance/velocity



NOW HOW DO I CHANGE THIS INTO HOURS.

FOR THIS PROBLEM I GOT FOR T= 4.6 FOR THE SECOND PART

AND 5.6 FIRST PART
