Solve the problem of the week below for your grade level. During your @HOME session, be sure to tell your instructor or email the Math Centre your answer so your ballot can be deposited into your grade level entry box before closing time on Friday. Students attending "in-Centre" sessions can deposit their ballots in their grade level entry box any time they are in the Math Centre during the week. On Friday afternoon (2:00pm), a ballot will be drawn from each Problem of the Week Entry Box and the first “correct” solution drawn from each box will win a Fabulous $10 Gift Card. All other “correct” Mathlete solutions entered will receive “2” extra punches on their Reward Card at the start of their next session in the Math Learning Centre.

Give your brain a workout.

Be sure to enter at the start of your next session at the Math Learning Centre.

Problem of the Week for Grades 3 and 4:  Derek has won 3 awards. Hansel has won 1 award. What fraction of all the awards did Derek win?

Problem of the Week for Grades 5 and 6:  Gasoline costs $1.15 per litre. If a car’s gas tank holds 55 litres in total and is only ¹/₅ full right now, then how much will it cost to fill up the tank?

Problem of the Week for Grades 7 and 8:  An ant is ¹/₆ of a centimetre tall. A middle school student is 1¹/₅ metres tall. The student goes to a learning centre that is 18 metres tall. If we scale by height, then how tall would a learning centre for ants be?  

Problem of the Week for Grades 9 and above:  A man throws a computer off of a platform straight to the ground. It falls 5 metres and hits the ground in half of a second. Consider this equation for vertical distance travelled in terms of initial velocity, time, and acceleration due to gravity (9.8 m/second²):

(distance) = (initial velocity)(time) – 0.5(acceleration due to gravity)(time)²

What is the initial velocity of the computer?
