The flight time was 8 hours 12 minutes.
Work out the average speed of the plane.
(3)
| Scheme | Marks |
|---|---|
For [8 hours 12 minutes =] 8.2 [hours] or \(8\dfrac{12}{60}\) oe or \(\dfrac{41}{5}\) oe or 8 × 60 + 12 (= 492) [minutes] | B1 |
[Average speed =] \(\dfrac{5658}{8.2}\) oe \(\dfrac{5658}{\text{“}492\text{”}} \times 60\) oe | M1 |
| Working not required, so correct answer scores full marks (unless from obvious incorrect working) Answer: 690 | A1 |

| (3 marks) |
Notes
B1: for correctly writing the time as a time in hours or minutes or for a correct calculation to do this
M1: for use of speed = distance ÷ time (use of their time in hours – if used minutes, then must multiply by 60)
(allow 5658 ÷ 8.12 (= 696.79…) for this mark if B0 awarded (allow 696 – 697))
