Question

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.

Answer 1

630=(r+35)time
455=(r-35)time

Divide the second equation into the first...

630/455= (r+35)/(r-35)

solve for r.
