Driving Is Expensive: Write A Program With Car's Miles Per G

Driving Is Expensive Write A Program With A Cars Milesgallon And Ga

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.58 7.89 63.04. Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem.

First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.

Paper For Above instruction

The cost of driving a vehicle over a certain distance can be calculated based on the fuel efficiency of the vehicle and the current fuel prices. This paper explores the equations used to determine the fuel cost for specified distances, focusing on the relationship between miles per gallon (mpg), dollars per gallon, and the resultant cost per distance, with practical applications and programming implementation details.

Introduction

Understanding the expenses associated with driving is crucial for drivers who wish to manage their budgets effectively. Fuel costs constitute a significant portion of overall vehicle expenses, and calculating these costs accurately requires understanding key parameters such as miles per gallon (mpg) and fuel prices per gallon. This paper examines how to develop a computational model that determines the monetary cost of driving specific distances based on vehicle efficiency and fuel prices.

Fuel Efficiency and Cost Calculation

The primary parameters involved are the miles per gallon (mpg) of the vehicle and the dollars per gallon (cost of fuel). The target is to compute the cost of fuel consumed over specific distances, in particular, 10, 50, and 400 miles. The fundamental formula involves converting the input data into a cost per mile and then multiplying by desired distances.

Mathematical Formulation

Given:

  • mpg (miles per gallon)
  • cost_per_gallon (dollars per gallon)

We first calculate the dollars per mile (dpm) as follows:

dpm = cost_per_gallon / mpg

This represents the cost to travel one mile. To find the total cost for a given distance, simply multiply the dollars per mile by the number of miles:

  • cost for 10 miles = dpm × 10
  • cost for 50 miles = dpm × 50
  • cost for 400 miles = dpm × 400

This process provides a straightforward way to estimate fuel costs over different travel distances based on simulated or real input data.

Implementation in Programming Language

To implement this in a programming language such as Python, one would first read user inputs for miles/gallon and dollars per gallon. Then, compute the dollars per mile and generate the costs for the specified distances. A sample implementation would involve the following steps:

miles_per_gallon = float(input())


dollars_per_gallon = float(input())


dollars_per_mile = dollars_per_gallon / miles_per_gallon


cost_10_miles = dollars_per_mile * 10


cost_50_miles = dollars_per_mile * 50


cost_400_miles = dollars_per_mile * 400


print(f"{cost_10_miles:.2f} {cost_50_miles:.2f} {cost_400_miles:.2f}")

Special attention should be given to handling floating-point output formatting to match precise expectations of output (e.g., two decimal places).

Practical Considerations and Limitations

While this model provides a good estimate of fuel costs, actual expenses could vary due to factors such as vehicle maintenance, depreciation, driving conditions, and fuel price fluctuations. Nevertheless, for basic calculations and budgeting, this model serves effectively.

Conclusion

The calculation of driving costs based on miles per gallon and the cost per gallon is a fundamental concept in automotive economics and personal finance. Using the described approach, drivers and developers can create efficient tools to estimate fuel expenses, facilitating informed decision-making regarding vehicle use and travel planning.
