s%5B1%5D is the speed for first portion
s%5B2%5D is the speed for the 2nd portion
s%5B1%5D+=+s%5B2%5D
s%5B1%5D+=+560%2Ft%5B1%5D
s%5B2%5D+=+480%2Ft%5B2%5D
t%5B1%5D+=+t%5B2%5D+%2B+1
560%2F%28t%5B2%5D+%2B+1%29+=+480%2Ft%5B2%5D
480t%5B2%5D+%2B+480+=+560t%5B2%5D
80t%5B2%5D+=+480
t%5B2%5D+=+6hours answer
