Cereal boxes assembled 4 minutes at a rate of 2 per second?

* Rate: 2 cereal boxes per second

* Time: 4 minutes

First, we need to convert the time from minutes to seconds:

* 4 minutes * 60 seconds/minute = 240 seconds

Now, we can calculate the total number of boxes assembled:

* 240 seconds * 2 boxes/second = 480 boxes

Therefore, 480 cereal boxes can be assembled in 4 minutes at a rate of 2 boxes per second.
