A polot flies 630 miles wit a tail wind of 35 miles per hour. Against the wind, he flies only 455 miles in the same amount of time. Find the rate of the plane in still air.

630=(r+35)time
455=(r35)time
Divide the second equation into the first...
630/455= (r+35)/(r35)
solve for r. 
I am still not coming up with the correct answer can you show me how to work it out??? Help

Thanks once again.. bobpursley
