Question

Liquid leaked from a damaged tank at a rate of r(t) liters per hour. The rate decreased as time passed and values of the rate at four-hour time intervals are shown in the table.

Find lower and upper estimates for the total amount of liquid that leaked out.

lower estimate = ??? liters

upper estimate = ??? liters

note: As the recorded rates most likely contain some amount of measurement error, it would be conventional to report findings as rounded decimals. This is because a value such as 25/2 suggests more accuracy in the answer than 12.5 would. So, for this problem, enter answers as decimal values (accurate to 4 decimal places)

Explanation / Answer

From the given table it is clear that the lower estimate will be 8.2 liters per hour and the upper estimate is 10.8 liters per hour.
