ivann1987 [24]

Answer:

3:45 PM.

Step-by-step explanation:

We have been given that on Thursday afternoon at camp Alice played basketball and went swimming before dinner she spent 45 minutes playing basketball and one hour swimming dinner lasted for an hour. The dinner ended at 5:30 PM.

Since she spent 1 hour for swimming, so 1 hour before 5:30 PM would be 4:30 PM.

To find the time, when Alice started playing basketball, we need to find 45 minutes before 4:30 PM.

30 minutes before 4:30 PM would be 4:00 PM and 15 minutes before 4:00 PM would be 3:45 PM.

Therefore, Alice started playing basket ball at 3:45 PM.

What is the of mexico
Lapatulllka [165]

Answer:

<h3>The answer is: what</h3>

Step-by-step explanation:

It's simple really, once you start writing a sentence you gradually begin to formulate a thought that needs to be built upon with the end goal being an effective paragraph or piece of information.

If you take "mexico" in this context you will need to include a what, in order to make a who. by "who" you could mean what, but in reality it's likely that mexico can be, in this case a "what"

So, the answer we arrive to is "what"
