1. Over time, a leaky faucet can waste many gallons of water. If a faucet drips at a rate of 2ounces per minute, how many gallons of water will be wasted in one week?(1 gallon = 128ounces)

Correct Answer: Correct answer is: (D) 157.5.

Exam Relevance: GRE, GMAT, Civil Engineering Exams, Environmental Science Exams

Difficulty: Moderate

Concept notes: The question involves calculating the total amount of water wasted over a week from a dripping faucet, converting ounces to gallons.

Common Mistakes: A common mistake is not correctly converting ounces to gallons or miscalculating the total time in minutes over a week.

Explanations: 1. Calculate the total number of minutes in a week: - There are 60 minutes in an hour. - There are 24 hours in a day. - There are 7 days in a week. - Total minutes in a week = 60 minutes/hour * 24 hours/day * 7 days/week = 10,080 minutes. 2. Calculate the total amount of water wasted in ounces: - The faucet drips at a rate of 2 ounces per minute. - Total water wasted in ounces = 2 ounces/minute * 10,080 minutes = 20,160 ounces. 3. Convert the total amount of water wasted from ounces to gallons: - 1 gallon = 128 ounces. - Total water wasted in gallons = 20,160 ounces / 128 ounces/gallon = 157.5 gallons. Thus, the total amount of water wasted in one week is 157.5 gallons.

Option Analysis:

Option A: 22.5 is incorrect because it is significantly lower than the correct amount.
Option B: 78.75 is incorrect because it is half of the correct amount.
Option C: 135 is incorrect because it is less than the correct amount.
Option D: 157.5 is the correct amount of water wasted in one week.
Option E: 9450 is incorrect because it is much higher than the correct amount.

Frequently Asked Questions

What are conversion factors in the context of water resources?

Conversion factors are used to change units of measurement, such as converting liters to cubic meters, to facilitate calculations and comparisons in water resource management.

How is drip rate relevant to water conservation?

Drip rate is crucial in water conservation as it measures the flow of water in irrigation systems, helping to minimize water waste and ensure efficient use of water resources.

What skills are necessary to understand water resource management?

Skills such as data analysis, critical thinking, and knowledge of environmental science are essential for understanding and managing water resources effectively.

How does water conservation impact the environment?

Water conservation helps preserve ecosystems, reduces the strain on natural water sources, and supports sustainable development by ensuring water availability for future generations.

What are some practical applications of water resource management?

Practical applications include irrigation systems, water treatment facilities, and policies that regulate water usage to ensure sustainable and equitable distribution of water resources.
