| 48 | A1 | |
| Alternative method 2 | ||
| A correctly evaluated multiple of 4 miles in the same multiple of 5 minutes | M1 | eg 8 (miles) in 10 (minutes) |
| their multiple of \(4 \times (60 \div\) their multiple of 5) | M1dep | eg \((4 \times 2) \times [60 \div (5 \times 2)]\) or \(8 \times 6\) |
| 48 | A1 | |
