Answer:
1/5 gallons per minute
Explanation:
The rate of flow of water is the slope of the line and the table
For container 1;
Using the coordinate points (10, 2) and (20, 4)
Rate of change =4-2/20-10
Rate of change = 2/10
Rate of change = 1/5 gallons per minute
For container two
Using the coordinates (5, 2) and (10, 4)
Rate of change = 4-2/10-5
Rate of change = 2/5 gallons/minute
Take their difference;
2/5 - 1/5
= (2-1)/5
= 1/5
Hence the difference between the rate of change is 1/5 gallons per minute
