 
 <translate> Jake has to descend 30 steps on 9 floors for a total of 9 * 30 = 270 steps. He descends 3 steps every second so he will descend 270 steps in 270 / 3 = 90 seconds. Austin will get down after only a minute (60 seconds) so Jake will get down 90 - 60 = 30 seconds later. So the final answer is 30. <hau> Jake dole ne ya sauko da matakai 30 a kan benaye 9 don jimlar 9 * 30 = matakai 270.
