Higher June 2022 Paper 1 Q13
13. The table shows the population and area of land for country X.
| Population | Area (km2) | |
|---|---|---|
| Country X | \(2{\cdot}16\times10^7\) | 3000 |
Population density can be measured in number of people per square kilometre.
The population density of country Y is 8000 people per km2.
Which country has the greater population density and by how much is it greater? [4]
| Scheme | Marks | Comments |
|---|---|---|
| \((2.16\times10^7)\div(3\times10^3)\) or 21 600 000 ÷ 3000 | M2 | M1 for \((2.16\times10^7)\div3000\) or an appropriate division with a place value error e.g. 216 000 000 ÷ 3000; implied by figs 72 |
| 7200 (people/km2) or \(7.2\times10^3\) | A1 | CAO; accept \(0.72\times10^4\) Do not ignore further incorrect working e.g. \(7.2\times10^3 = 72\,000\) is A0 |
| Y indicated and (8000 – 7200 = ) 800 (people/km2) | B1 | FT ‘their 7200’ and the country that matches their values provided at least M1 previously awarded; answer must be given as an integer or correctly expressed in standard form. |
