Explanation:

Step1: Find number of bags filled

The number of bags filled at 12 P.M. is 28 and at 3 P.M. is 65. So the number of bags filled between 12 P.M. and 3 P.M. is $65 - 28=37$.

Step2: Find time - interval

The time - interval from 12 P.M. to 3 P.M. is $3 - 0 = 3$ hours.

Step3: Calculate average

The average number of bags filled per hour is $\frac{37}{3}\approx12.3$.

Answer:

12.3
