Answer:
The walk to the park took the longest amount of time
Explanation:
In this question, we want to find the location that took Donovan the longest amount of time to work.
We should recall that an hour is 60 minutes
So time spent walking to the mailbox would be 2/15 * 60 = 8 minutes
Time spent walking to the library would be 1/6 * 60 = 10 minutes
Time spent walking to the park = 2/10 * 60 = 12 minutes
So as we can see, the distance taking the longest amount of time to walk is the Park which took a total of 12 minutes
