Flying against the wind, an airplane travels 8080 kilometers in 8 hours. Flying with the wind, the same plane travels 9030 kilometers in 7 hours. What is the rate of the plane in still air and what is the rate of the wind

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
