Maths: 2014 Auckland Marathon Math

This week for maths, we had to complete 2 hard and easy math problems. These 2 problems were about the 2014 Auckland Marathon, and our goal, was to find the time differences between the winner, and the average runner. The first problem, wasn't too challenging. Although the second problem had some problems. Firstly, the seconds were different from each other, so our math concluded of borrowing, and negative numbers. The way we solved the math is in a DLO, so it isn't necessary to explain what we did to figure it out. For this activity, I worked with Alex, and Julian, and got our worked checked by Ms Kirkpatrick.
