Jake has to descend 30 steps on 9 floors for a total of 9*30 = <<30*9=270>>270 steps

He descends 3 steps every second so he will descend 270 steps in 270/3 = <<270/3=90>>90 seconds.

Austin will get down after only a minute (60 seconds) so Jake will get down 90-60 = <<90-60=30>>30 seconds later.

Austin and Jake start descending from the 9th floor of a building at the same time. Austin uses the elevator and Jake uses the stairs, descending 3 steps every second. The stairs have 30 steps across each floor. If the elevator will take a minute to get to ground level, how many seconds later will Jake get to the ground floor?
