(a)
Ruby sets off by train at 8:40 and arrives at 10:10. How long does the journey take?
[1](b)
The journey is 117 km. Work out the average speed in km/h.
[2]The whole Core exam: Paper 1, Paper 2 and the mental test, each with its own clock.
| Paper | Time | Marks | Calculator |
|---|---|---|---|
| Paper 1 | 60 minutes | 100 | No |
| Paper 2 | 60 minutes | 100 | Yes |
| Mental arithmetic | 10 minutes | 40 | No |
| Additional (optional) | 60 minutes | 100 | Yes |
Use a quiet room and a simple scientific calculator for Paper 2 only. Leave the mental test for a separate moment: it is a different kind of speed.
