The lower and upper bounds of the total amount of water that comes out of the hose is 671.5 liters and 672.5 liters respectively.
How to calculate the lower and upper bounds of the total amount of water?
The lower and upper bounds of the total amount of water that comes out of the hose is calculated by applying the following formula.
total amount of water delivered = flow rate x time of flow
The given parameters include;
flow rate of the water = 2.1 liters / min
time of water flow = 320 mins
The total amount of water delivered is;
Q = 2.1 Liters / min x 320 min
Q = 672 liters
The lower bound of the total amount of water delivered is
= (672 - 0.5) Liters
= 671.5 liters
The upper bound of the total amount of water delivered is;
= (672 + 0.5) liters
= 672.5 liters
