03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 625 metres. | Sixty two thousand five hundred centimetres divided by 100 gives 625 m. |
| 2 | Ten centimetres. | Two thousand five hundred metres divided by 250 m per centimetre gives ten. |
| 3 | Twenty per cent. | One hundred and fifty divided by 750 is 0.2, which is 20 per cent. |
| 4 | Forty five minutes. | The track is 4.5 km, which at 6 km per hour takes 0.75 hour, or 45 minutes. |
| 5 | 1.5 square kilometres. | The field is 1.5 km by 1 km, giving 1.5 square kilometres. |
| 6 | Twenty five per cent. | Four millimetres covers 80 m, and 20 over 80 gives 25 per cent. |
| 7 | 1 120 metres. | Divide by 1.5 to recover 5.6 cm, then multiply by 200 m per centimetre. |
| 8 | 50 cm and 5 cm. | At 1:10 000 a centimetre covers 100 m, while at 1:100 000 it covers 1 000 m. |
| 9 | Ten per cent. | A drop of 200 m over 2 000 m gives 0.1, or ten per cent. |
| 10 | The unit conversion. The answer should be 2 000 m, or 2 km. | Ten centimetres times 20 000 gives 200 000 cm, which must be divided by 100 to become metres. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
An algorithm is a finite and unambiguous list of steps; flowcharts use a diamond for decisions and a parallelogram for input or output, combined through sequence, selection and iteration.Tutor Registration →
