Use unit analysis to solve this problem. In one hour there are 60 minutes and in one day there are 24 hours. That is, hr/60min and day/24hr (The division can be pronounced "per", as in "60 minutes per hour" or "one hour per 60 minutes") Using these two terms, divide out the minutes and multiply in the days: 3500min * hr/60min * day/24hr The "min" units in the numerator of 35000 cancels out with the 60 min in the denominator of hr/60min. Same with the "hr". What you are left with is 3500 * 1/60 * 1day/24 Multiplying this out is approximately 2.43 with the unit of "days" left in the numerator.

When choosing repeating variables in dimensional analysis, it is important to select variables that have a significant impact on the problem and are independent of each other. This helps ensure that the analysis is accurate and meaningful.
Dimensional analysis is important because it allows us to check the consistency of equations by ensuring that the units on both sides of the equation are the same. It helps in deriving relationships between physical quantities and simplifies problem-solving by reducing the number of variables involved. Additionally, dimensional analysis can be used to convert units and provide insight into the underlying physics of a problem.
Dimensional analysis is useful in scientific calculations and problem-solving because it helps ensure that the units of measurement are consistent throughout the calculations. This method allows scientists to check the accuracy of their calculations and identify any errors that may have occurred. By using dimensional analysis, scientists can easily convert units and solve complex problems without making mistakes in the process.

The process of writing units of each variable in a real-life problem is called dimensional analysis or unit analysis. It is useful for understanding the real-life problem and for checking to see we get a valid answer. Please see the links for additional explanations.
The numerator is the top number in any fraction.
It is also called "Dimensional Analysis". It is a problem-solving method that uses the fact that any numbers can be multiplied by one without changing its value.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value
Use dimensional analysis to solve this problem! 140 inches x (1 foot/12 inches) = 11.667 feet or (35/3) feet
