Final answer:
Alice took 60 minutes on her first trial, and the time reduces by 10 percent per trial. On the second trial, she would take 54 minutes.
Step-by-step explanation:
Alice took 60 minutes to complete the task on her first trial, and she reduces the time by 10 percent per trial. To find the time taken on the second trial, we need to calculate 10 percent of 60 minutes, which is 6 minutes. Then, we subtract the 6 minutes from the initial time of 60 minutes. So, the time taken on the second trial would be 60 minutes - 6 minutes = 54 minutes.
