|---|---|---|---|
| 610.7 to 632.2 | 5 | B2 for 1425 to 1475 or B1 for 11.4 to 11.8 or M1 for their length \(\times\) 125 ANDB1 for \(2\frac{1}{3}\), 2[h] 20 or 2.33… or 140 and M1 for distance ÷ time and A1FT ft for a correct answer for their length | See additional guidance This calculation must be seen and distance must be their measurement or their measurement \(\times\) 125. You must be convinced that it is a time as a divisor. |
