Chapter 1: Problem 74

Change 1 h 25 min to min.

Short Answer

Expert verified
1 hour 25 minutes is 85 minutes.

Step by step solution

01

Identify Components

First, let's recognize the components we have: 1 hour and 25 minutes. Our goal is to convert all of this time into just minutes.
02

Convert Hours to Minutes

Since 1 hour is equal to 60 minutes, we need to convert the hours into minutes. So, we have: \[1 \text{ hour} = 60 \text{ minutes}\]
03

Add the Remaining Minutes

Now we take the 25 minutes and add it to the 60 minutes we calculated from Step 2.So, we calculate:\[60 \text{ minutes (from 1 hour)} + 25 \text{ minutes} = 85 \text{ minutes}\]
04

Final Calculation

Summing up, the total number of minutes from 1 hour and 25 minutes is 85 minutes. So, \[1 \text{ hour and } 25 \text{ minutes} = 85 \text{ minutes}\]

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Time Conversion
Time conversion is a fundamental skill, especially useful when dealing with different time units in various contexts. In this example, we convert a mixed time format, 1 hour and 25 minutes, completely into minutes.

The key to a successful time conversion is understanding the relationship between different units of time. Here, we need to remember that 1 hour is equivalent to 60 minutes. This relationship allows us to easily convert hours into minutes by multiplying the number of hours by 60.

Once the hours are converted, you simply add any remaining minutes to get the total in minutes. This methodical conversion ensures accuracy and simplifies calculations involving time.
Mathematical Steps
Breaking down the process into clear mathematical steps is essential for problem-solving. Here鈥檚 how we approached the conversion process:

  • Step 1: Identify the components - Recognize that we have 1 hour and 25 minutes.
  • Step 2: Convert hours to minutes - Multiply the number of hours by 60, which gives us 60 minutes from 1 hour.
  • Step 3: Add the remaining minutes - Combine the already converted minutes with the remaining 25 minutes to simplify calculation: \(60 + 25 = 85\) minutes.


These simple steps demonstrate how breaking down a problem into manageable parts can make it easier to solve, especially in mathematical contexts.
Educational Example
This exercise serves as an excellent educational example to illustrate the practical application of unit conversion within the everyday context of measuring time.

By using a step-by-step approach, students can visually and logically follow the process of conversion. This helps in enhancing their understanding and retention of the concept.

By regularly practicing these kinds of examples, it becomes easier for learners to tackle more complex problems in the future, as they build a strong foundation in basic arithmetic and unit conversion.
