Days between events

Worked solution

1. 1

   Begin at the first visit, 4 June.

   $0\text{days passed}$

   The starting date does not represent a day that has already passed.

2. 2

   Count each move to the next date.

   $\begin{array}{rl}5,6,7,8,9\text{June}& \\ 1,2,3,4,5\text{days passed}& \end{array}$

   The fifth one-day move reaches the second visit on 9 June.

3. 3

   Check with the date difference.

   $9-4=5$

   Both dates are in June, and the count confirms that five days pass.

Worked solution

1. 1

   Move forward one day from 29 June.

   One day later is 30 June; the start date itself is not counted.

2. 2

   Move forward a second day.

   June ends on the thirtieth, so the next date is 1 July.

3. 3

   Make the third one-day move.

   Three days later is 2 July, which is the camp’s end date.
