Answer to Problem 11P

The amount of fuel consumed on average daily basis in gallons/day is 2.47×108gallons/day_.

The amount of fuel consumed on average daily basis in liters/day is 9.36×108liters/day_.

Explanation of Solution

Given information:

The average distance travelled by the car is 12,000 miles per year.

The gas consumption rate of the car is 20 miles/gallon.

The sample size is 150 million cars.

Calculation:

Find the amount of fuel consumed on average daily basis using the relation.

{Amountoffuelconsumedonaverage dailybasis}=Averagedistance×NumberofcarsGasconsumptionrate=12,000milesyear×1year365days×150×10620milesgallon=2.47×108gallons/day

Therefore, the amount of fuel consumed on average daily basis as 2.47×108gallons/day_.

Convert the units from gallons/day to liters/day.

Amountoffuelconsumed=2.47×108gallons/day×3.79liters1gallons=9.36×108liters/day

Therefore, the amount of fuel consumed on average daily basis as 9.36×108liters/day_.

Answer to Problem 11P

The amount of fuel consumed on average weekly basis in gallons/week is 1.73×109gallons/week_.

The amount of fuel consumed on average weekly basis in liters/week is 6.56×109liters/week_.

Explanation of Solution

Given information:

The average distance travelled by the car is 12,000 miles per year.

The gas consumption rate of the car is 20 miles/gallon.

The sample size is 150 million cars.

Calculation:

Find the amount of fuel consumed on average weekly basis using the relation.

{Amountoffuelconsumed on average weekly basis}=Averagedistance×NumberofcarsGasconsumptionrate=12,000milesyear×1year52weeks×150×10620milesgallon=1.73×109gallons/week

Therefore, the amount of fuel consumed on average weekly basis as 1.73×109gallons/week_.

Convert the units from gallons/weekly to liters/weekly.

Amountoffuelconsumed=1.73×109gallons/week×3.79liters1gallons=6.56×109liters/week

Therefore, the amount of fuel consumed on average weekly basis as 6.56×109liters/week_.

(c)

Answer to Problem 11P

Therefore, the amount of fuel consumed on average monthly basis in gallons/month is 7.5×109gallons/month_.

Therefore, the amount of fuel consumed on average monthly basis in liters/month is 28.43×109liters/month_.

Explanation of Solution

Given information:

The average distance travelled by the car is 12,000 miles per year.

The gas consumption rate of the car is 20 miles/gallon.

The sample size is 150 million cars.

Calculation:

Find the amount of fuel consumed on average monthly basis using the relation.

{Amountoffuelconsumed on average monthly basis}=Averagedistance×NumberofcarsGasconsumptionrate=12,000milesyear×1year12months×150×10620milesgallon=7.5×109gallons/month

Therefore, the amount of fuel consumed on average monthly basis as 7.5×109gallons/month_.

Convert the units from gallons/month to liters/month.

Amountoffuelconsumed=7.5×109gallons/month×3.79liters1gallons=28.43×109liters/month

Therefore, the amount of fuel consumed on average monthly basis as 28.43×109liters/month_.

(d)

Answer to Problem 11P

The amount of fuel consumed on average yearly basis in gallons/year as 9×1010gallons/year_.

The amount of fuel consumed on average yearly basis in liters/year as 34.11×1010liters/year_.

Explanation of Solution

Given information:

The average distance travelled by the car is 12,000 miles per year.

The gas consumption rate of the car is 20 miles/gallon.

The sample size is 150 million cars.

Calculation:

Find the amount of fuel consumed on average yearly basis using the relation.

{Amountoffuelconsumed on average yearly basis}=Averagedistance×NumberofcarsGasconsumptionrate=12,000milesyear×150×10620milesgallon=9×1010gallons/year

Therefore, the amount of fuel consumed on average yearly basis as 9×1010gallons/year_.

Convert the units from gallons/year to liters/year.

Amountoffuelconsumed=9×1010gallons/year×3.79liters1gallons=34.11×1010liters/year

Therefore, the amount of fuel consumed on average yearly basis as 34.11×1010liters/year_

Answer to Problem 11P

The amount of fuel consumed over a period of 10 years in gallons is 9×1011gallons_.

The amount of fuel consumed over a period of 10 years in liters is 34.11×1011liters_.

Explanation of Solution

Given information:

The average distance travelled by the car is 12,000 miles per year.

The gas consumption rate of the car is 20 miles/gallon.

The sample size is 150 million cars.

Calculation:

Find the amount of fuel consumed over a period of 10 years basis using the relation.

{Amountoffuelconsumed over a period of 10 years}=Averagedistance×Numberofyears×NumberofcarsGasconsumptionrate=12,000milesyear×10years×150×10620milesgallon=9×1011gallons

Therefore, the amount of fuel consumed over a period of 10 years as 9×1011gallons_.

Convert the units from gallons to liters.

Amountoffuelconsumed=9×1011gallons×3.79liters1gallons=34.11×1011liters

Therefore, the amount of fuel consumed over a period of 10 years as 34.11×1011liters_.

Question 3 (20 points): The traffic volume on a 2-lane highway is 1600 veh/hr in each direction Page 3 of 6 with a density of 20 veh/mi. A large dump truck enters the traffic stream from an adjacent construction site at 20 mph and carries on this way for 2 miles before turning off to the dump site. Because flow is so high in the opposite direction, no one can pass the truck. As a result, traffic back up behind the truck at four times the density (i.e., 4x20 = 80 veh/mi) at a volume of 1000 veh/hr. How many vehicles get caught in the traffic congestion before the truck exits the highway?
How can construction project managers find a balance between speeding up schedules and the risks of making more mistakes and needing rework, especially when using methods like fast tracking?
