2.5 seconds
Explanation:
The amount remaining in the full bucket is ...
40 -8t . . . . . ounces, where t is in seconds
The amount in the empty bucket is ...
8t
These are equal when ...
40 -8t = 8t . . . . . an equation with variables on both sides
The solution is ...
40 = 16t
40/16 = t = 2.5
The buckets will have the same amount after 2.5 seconds.
