Lesson 1-8 Problem Solving Investigation

Work Backward

The closing day activities at Coach Elam’s basketball camp must be over by 1:30 P.M. She needs 45 minutes for the All-Star game, 30 minutes for the awards presentation, 1 hour 15 minutes for the final league games, and 20 minutes for stretching and warm-up. At what time should the day begin?

Understand	You know the time that the basketball camp should end. You know the time it takes for each activity. You need to determine the time the day’s activities should begin.

Plan		Start with the ending time and work backward.	

Solve		The day is over at 1:30 P.M.

		Go back 20 minutes for stretching and warm-up.	1:10 P.M.
		Go back 1 hour 15 minutes for league games.	11:55 A.M.
		Go back 30 minutes for the awards presentation.	11:25 A.M.
		Go back 45 minutes for the All-Star game	.	10:40 A.M.

		So, the camp should start no later than 10:40 A.M.

Check		Work forward starting at 10:40 A.M.
