1MA0 Higher November 2016 Paper 2 Q6
6 Jack is building a wall.
He uses 300 bricks to build part of the wall.
This part of the wall is 5 metres long and 1.5 metres high.
The complete wall will be 8 metres long and 1.5 metres high.
How many more bricks does Jack need to complete the wall? (3)
| Answer | Mark | Notes |
|---|---|---|
| 180 | 3 | M1 for a correct start to the process, eg \(300 \div 5\) (= 60) or \(300 \div (5 \times 1.5)\) (= 40) or \(8 \div 5\) (= 1.6) or \(5 \div 8\) (= 0.625) M1 for a complete method that will lead to the number of bricks needed to build the wall (= 480) or for a complete method that will lead to the number of extra bricks needed to build the wall, eg \(300 \div 5 \times 3\) A1 cao |
