You can put this solution on YOUR website!
560+=+s%2A%28t+%2B+1%29
480+=+s%2At
I have 2 equations and 2 unknowns, so I should be able to solve for s & t
s+=+560+%2F+%28t+%2B+1%29
s+=+480+%2F+t
560+%2F+%28t+%2B+1%29+=+480+%2F+t
560t+=+480t+%2B+480
80t+=+480
t+=+6hrs answer
---------------------
To check, solve for s in both equations- they should be equal
560+=+s%2A%28t+%2B+1%29
480+=+s%2At
560+=+7%2As
s+=+80 mi/hr
480+=+6%2As
s+=+80 mi/hr
OK
