Beth met her friends at the library at 4:30 PM it's took her 24 minutes to walk from her house to the library what time did Beth leave her house to arrive at the library at exactly 4:30 PM

04:06 PM

Step-by-step explanation:

Beth met her friend at 04:30 PM that means she reached library at that time. As it is mentioned that it takes her 24 minutes to walk from home to library.

Since she reached library at 04:30, we have to subtract 24 minutes out of 04:30 (Go 24 minutes back) to get the time when she left the home.

So,

subtracting 24 gives us 04:06 PM.

Beth left her home at 04:06 PM ...
