Hank is painting his grandfather's fence. he painted 40 linear feet in 85 minutes. he still has 360 linear feet to paint. his cousins, sam and alex, come to . sam paints twice as fast as hank, and alex paints half as fast as hank. find the constant of proportionality for the fence painting rate of hank, sam, and alex combined. (round to nearest tenth)

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?
