|---|---|---|
| Yes (supported) | P1 | for process shown to add a time to departure time eg \(8.45 + 0.17\) or \(8.45 + 0.15\) or \(8.45 + 0.15 + 0.17\) OR for process to work out time at work after arrival at Manchester bus stop eg \(\text{``}9.35\text{''} + 15\) OR finds accumulated additional time eg \(17 + 15\ (= 32)\) OR start to work backwards eg \(10.00 - 0.15\) |
| P1 | for process to use a bus time from Whitefield to Manchester with other times eg 0904 to 0935 with use of 17 or 15 | |
| C1 | for conclusion of “Yes” supported by correct figures eg states 9.50 or comparable figures eg 9.35 and 25 (spare) |
Additional guidance
There must be some attempt to add but not necessarily complete or correct (eg 8.62). “9.35” must be a given time ie from 0905, 0935, 0955, 1010, 1025, or 1048.
Process must be shown.
Do not award in cases of ambiguity.
There needs to be a conclusion eg Yes or equivalent words supported by correct figures; if C mark fully evidenced award 3 marks.

| Answer | Mark | Mark scheme |
|---|---|---|
| Yes (supported) | P1 | for process shown to find a duration of time using given figures eg 8.45 to 10.00, 8.34 to 9.05, 10.14 to 10.48 |
| P1 | for process to find the total travelling time eg \(17 + 31 + 15\) or \(17 + 2 + 31 + 15\) | |
| C1 | for conclusion of “Yes” supported by correct figures eg comparable figures eg \(65 \lt 75\) or \(75 - 65\ (= 10)\) |
Additional guidance
There must be some attempt to find a duration of time but not necessarily complete or correct.
Process must be shown.

There needs to be a conclusion eg Yes or equivalent words supported by correct figures; if C mark fully evidenced award 3 marks.
