Iina finished a puzzle in 7 minutes. How many seconds is this?
The Correct Answer and Explanation is:
To convert 7 minutes into seconds, we use the fact that there are 60 seconds in one minute.
The conversion process is simple:
1 minute = 60 seconds
Therefore, 7 minutes = 7 × 60 seconds = 420 seconds.
Explanation:
When dealing with time conversions, you need to recognize the relationship between different units of time. Here, we’re converting from minutes to seconds, so the factor of conversion is 60 seconds per minute.
Step 1: Identify the units and conversion factor.
In this case, the given time is in minutes, and you are converting it to seconds. The standard conversion factor is 60 seconds per 1 minute.
Step 2: Multiply the number of minutes by the conversion factor.
Since 7 minutes is the time given, you multiply it by 60 to find the number of seconds.
Step 3: Calculate.
7 × 60 = 420 seconds. This is the time it takes Iina to finish the puzzle.
This basic concept of unit conversion is applicable to many scenarios in everyday life, like converting hours to minutes or days to hours. It’s useful in various fields like science, travel, and even cooking!
