How far did the truck travel in April?
Give your answer in kilometres. [3]
| Scheme | Marks | Comments |
|---|---|---|
| \(\pi \times 1.22\) (m) or \(\pi \times 0.00122\) (km) | M1 | Or equivalent Allow M1 for \(\pi \times 1.22 \times n\) or \(\pi \times 0.00122 \times n\) where \(n \gt 1\) |
| \(\times\ 2.4 \times 10^{6}\) | m1 | |
| For an answer in the range 9193 to 9200 (km) | A1 | CAO. No FT from incorrectly considering more than 1 wheel |
