The plane flies a distance of 1512 kilometres.
Work out the average speed of the plane.
Give your answer in kilometres per hour. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 630 | M1 | for converting time, eg 24 minutes = \(\dfrac{24}{60}\) (= 0.4 (hours)) oe eg \(\dfrac{2}{5}\) (hours) or 2 hours 24 minutes = \(2 + \dfrac{24}{60}\) (= 2.4 (hours)) oe eg \(2\dfrac{2}{5}\) (hours) or 2 hours 24 minutes = \(2 \times 60 + 24\) (= 144 (minutes)) oe or 2 hours 24 minutes = \(2 \times 60 \times 60 + 24 \times 60\) (= 8640 (seconds)) oe OR for using distance \(\div\) time, eg \(1512 \div [\text{time}]\) oe or \([\text{distance}] \div [\text{time}]\) oe |
| M1 | for a complete method using distance \(\div\) time, eg \(1512 \div \text{``}2.4\text{''}\) or \(1512 \div \text{``}2\tfrac{2}{5}\text{''}\) or \(1512 \div \text{``}144\text{''} \times 60\) oe or \(1512 \div \text{``}8640\text{''} \times 60 \times 60\) oe | |

Additional guidance
10.5 or 0.175 imply M1
[distance] can be 1512 or the result of an attempt to convert 1512 km to a different unit, it must have the digits 1512 eg 151.2 or 1 512 000
[time] can be any value they believe to be the time the plane takes to fly
