Ahigh -speed elevat6 can rise 480 feet in 30 seconds. which expression represent the rate, in fret per minute, of elevator?

If an elevator rises 480 feet per 30 seconds, then it would rise 960 feet per minute.

You get this answer by doubling 480 because there are 60 seconds in a minute, and you have to also double 30 seconds to get 60 seconds. 960ft/1min is the answer. 

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?
