If Jeff spent 11 more minutes cleaning his room than Todd, and Jeff spent a total of 43 minutes, we can use algebra to solve for Todd's cleaning time:
Let t be the time Todd spent cleaning his room.
Then Jeff spent t + 11 minutes cleaning his room.
We know that Jeff spent a total of 43 minutes cleaning his room, so we can set up an equation:
t + 11 = 43
Subtracting 11 from both sides, we get:
t = 32
Therefore, Todd spent 32 minutes cleaning his room.
