Final answer:

The average rate that the sand is filling the truck between two and four minutes is 55 pounds per minute.

Explanation:

To find the average rate that the sand is filling the truck between two and four minutes, we need to calculate the rate of change in the amount of sand over the time interval.

The change in the amount of sand is 238 pounds - 128 pounds = 110 pounds.

The time interval is 4 minutes - 2 minutes = 2 minutes.

So, the average rate is 110 pounds / 2 minutes = 55 pounds per minute.
