Answer 1

When adding or subtracting time, it's crucial to remember to convert hours to minutes as needed. For subtraction, we may need to borrow an hour and convert it to 60 minutes to continue, and for addition, we simply add up like units for the final sum.

Step-by-step explanation:

When working with time units, it's important to be able to add and subtract minutes and hours with ease. This involves understanding that 1 hour equals 60 minutes and using this to borrow or carry over minutes when necessary.

• For example, to subtract 30 minutes from 5 hours and 10 minutes, you first convert the time to 4 hours and 70 minutes.
• Then subtract the minutes directly: 4 hr 70 min - 30 min = 4 hr 40 min.
• To add 45 minutes to 1 hour and 5 minutes, you add the minutes giving a total of 1 hr 50 min.

By understanding these principles, solving various time addition and subtraction problems becomes straightforward.
