| Calculates the total hours already used. (tennis 1/12 of 24 =) 2 (hours) OR (working 3/8 of 24 =) 9 (hours) | M1 | |
| (Hours left) 24 – (8 + 2 + 9) = | m1 | FT provided 2 hours or 9 hours correct. (Candidates MUST have made a convincing attempt at calculating 2 AND 9) |
| e.g. ‘5 hours is more than 2 so yes, Omar will have enough time’ ‘only adds to 21 (hours) so enough time’ ‘21 is less than 24, so yes’ ‘5 (hours left, Omar has) enough time’. | A1 | CAO |
