Water Jug If a completely full 5-gallon water jug is drained through a spigot, the depth is given by the formula
Where t is the time, in minutes, that the spigot is open and D is the depth, in inches, above the spigot.
a. Make a graph of D versus t. Include values of t up to 7.5 minutes.
b. Calculate
c. When will the water jug be completely drained?
d. Does the water drain faster near the beginning or when the water is mostly drained?
