Problem of the Week
By Trudy Gau
Due to Curriculum Day on Monday, I did not get a chance to announce winners. All winners will be announced at our final assembly on Friday 19th September.
Mild:
Which elements are in the wrong place? Where should they be?
Medium:
A telephone call costs 25c for 3 minutes and then 3c for each additional minute. If Jason spends 40c for his call, how long was his call?
Spicy:
The clock below loses 12 minutes every hour. It shows the correct time now. How long will it be before it shows the correct time again?
