Final answer:
The sum of 25 and 60 is 85. This is a simple arithmetic addition. Similar processes are used when adding and converting different units of time.
Step-by-step explanation:
The sum of 25 and 60 is equivalent to 85. This answer is reached by simply adding the two numbers together, which is a basic arithmetic operation. Below we have some examples of how this process works with various units of time:
15 minutes + 60 minutes = 75 minutes
10 minutes + 20 minutes = 30 minutes
15 seconds + 45 seconds = 60 seconds, which is equivalent to 1 minute
Similarly, when converting and adding time:
1 hour 5 minutes + 45 minutes = 1 hour 50 minutes
100 minutes can be simplified to 1 hour 40 minutes, because 60 minutes equal 1 hour
120 seconds divided by 60 seconds per minute = 2 minutes
To convert 4 hours to minutes: 4 hours * 60 minutes per hour = 240 minutes
And when adding measures of time that exceed the standard unit:
1 hour 55 minutes + 45 minutes = 1 hour 100 minutes, which simplifies to 2 hours, because 60 minutes equal 1 hour
