There are two million autos in a given jurisdiction, each of which travels 300 miles per week at 21 miles per gallon. The average gas station has a six-day inventory on hand, stored in underground tanks. The typical auto has a gas tank that is 38% filled (capacity=15 gallons).
a. Compute the average daily deliveries to the gas stations to maintain the above equilibrium. ________gal/day
b. Compute the "moving storage" in gallons. _______gal-stored -in-auto-tanks
c. Compute the "moving storage in days of inventory onboard vehicles. __________days-suppy-stored-in-auto-tanks
d. A rumor that an interruption in gas supply will occur. Drivers immediately increase their average gas in their auto to a percent filled of 58% rather than 38%. IN addition, drivers begin only travelling 250 miles per week instead of 300. Can the gas stations meet the immediate demand created by the increase from 38% to 58% filled? Show why or why not
e. How long will it be before the gas stations return to a six day inventory, given 250 miles per week driving, constant gas supply, and tanks 58% filled?______days required
