How to Add and Subtract Mixed Time Units

A Step-by-step Guide to Adding and Subtracting Mixed Time Units

Here’s a step-by-step guide on how to add and subtract mixed time units:

Step 1: Understand the time units

First, it’s important to understand the relationship between different units of time:

• 1 hour = 60 minutes
• 1 minute = 60 seconds

Step 2: Convert all time to the same unit

Before you can add or subtract, you should convert all time to the same unit. If you’re working with hours and minutes, convert everything to minutes. If you’re working with minutes and seconds, convert everything to seconds.

Step 3: Perform the operation

Once all time is in the same unit, add or subtract as the problem requires.

Step 4: Convert back if necessary

Once you’ve added or subtracted, you might need to convert your answer back to mixed units.
