Foundation November 2019 Paper 2 Q15
15 The length of a plane is 19.2 metres.
Lukas buys a scale model of the plane.
The scale of the model is \(1 : 24\)
Work out the length of the scale model of the plane.
Give your answer in centimetres. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 80 | M1 | for converting to cm |
| M1 | for use of scale eg \(19.2 \div 24\ (= 0.8)\) or \(1920 \div 24\) or [length] \(\div\ 24\) | |
| A1 | cao |
Additional guidance
Can be done at any stage of the problem
eg \(19.2 \times 100\ (=1920)\) or \(0.8 \times 100\)
[length] must come from an attempt to change 19.2 metres into cm
