8. It takes 3 people 6 days to mow a grass verge.
(a) How many days would it take 9 people to mow a grass verge that is twice as long? [2]
(b) State one assumption you have made in answering this question. [1]
| Scheme | Marks | Comments |
|---|---|---|
| 4 (days) | B2 | B1 for either a partial method, e.g. 9 people take 2 days to mow the same length, or 1 person takes 36 days (to mow twice as long), or 3 people take 12 days (to mow twice as long), OR B1 for a full method, equivalent to 2 × 3 × 6 ÷ 9, with an error in evaluation |
| Scheme | Marks | Comments |
|---|---|---|
| Assumption, e.g. ‘all people work at the same rate’, ‘the grass verge that is twice as long is the same width as the other grass verge’, ‘same type of grass’, ‘weather is the same’, ‘same type of mower’ | E1 | The award of this mark depends on the award of B2 or B1 in (a) Allow as a misinterpretation, e.g. ‘takes the same time cutting grass twice as long’, ‘the original 3 people will take 12 days to mow twice as long grass verge’ |
