Tom takes 1 day to clear 1 acre.
To find out how many days it takes Tom to clear 1 acre, we can calculate the rate at which he clears brush in acres per day.
Let's use the given information:
acre cleared in 2 days,
acres cleared in 5 days,
acres cleared in 7 days.
First, let's find the rate in acres per day for each interval:
For the first interval:
acre per day.
For the second interval:
acre per day.
For the third interval:
acre per day.
It appears that the rate at which Tom is clearing brush is consistent at
acre per day.
Therefore, Tom takes 1 day to clear 1 acre.
