The function   is an decreasing function.
The number of intervals is  
Each interval value is  

Step-by-step explanation

Step 1.
The distance approximation provides the lower estimate for the total amount of oil leaked from the tank and provides the upper estimate for the total amount of oil leaked from the tank.
The expression to find the lower estimate for the total amount of oil leaked is shown below:
   
Here, for the time , the rate is , the time interval is , for the time , the rate is , and for the time , the rate is .
Substitute 5 for in Equation (1).
 
Substitute   for for for for  for , and for   in Equation (2).
 
 
 
Therefore, the lower estimate for the total amount of oil leakage from tank is  .
