It takes 15 minutes for Dante to go to Hidden Lake. From Hidden Lake, he has to walk back to the Park Office and it takes him 7 minutes. When he arrives there, he will have been gone from the Park Office 32 minutes altogether. If he had walked to the Lake Park restaurant from the Park office before taking the 15 minute walk to Hidden Lake, how long is the walk from Park Office to the Lake Park restaurant? Think carefully first, then make a decision:
If it takes 15 minutes for Dante to go to Hidden Lake and 7 minutes to walk back to the Park Office, he spends a total of 15 + 7 = 22 minutes on the trip. When Dante arrives at the Park Office, he will have been gone from the Park Office 32 minutes altogether, and since he passed by the Lake Park restaurant from The Park Office, his walk from Park Office to the Lake Park restaurant took 32 - 22 = 10 minutes. So, the answer is 10.
