How many minutes are in 2 hours?
A. 2 minutes
B. 20 minutes
C. 60 minutes
D. 100 minutes
E. 120 minutes
The correct answer and explanation is:
The correct answer is E. 120 minutes.
To explain, time is divided into various units: seconds, minutes, and hours. Each hour contains 60 minutes. Therefore, to calculate the number of minutes in 2 hours, you simply multiply the number of minutes in one hour (60) by 2.
Mathematically, it looks like this: Number of minutes in 2 hours=60×2=120\text{Number of minutes in 2 hours} = 60 \times 2 = 120
This calculation follows the basic principle that an hour is always 60 minutes long, regardless of the context in which it is measured. This is standardized globally. So, in this case, if you are given 2 hours, multiplying by 60 will always give you the correct result of 120 minutes.
It is important to understand that converting between hours and minutes is a straightforward calculation, where 1 hour equals 60 minutes. This relationship is part of the metric time system, which is universally accepted and used in various aspects of daily life, including scheduling, cooking, travel, and work.
If you ever need to convert from minutes back to hours, you can simply divide the number of minutes by 60. For example, if you had 120 minutes, you would divide it by 60 to get 2 hours.
This conversion is key to managing time effectively in daily routines, and it’s helpful to remember that hours and minutes are directly related in this way.
