| Answer | Mark | Mark scheme |
|---|---|---|
| 50 | B1 | for finding the time difference, eg, 1 hr 18 mins or 78 mins oe |
| P1 | for correct process to convert minutes to hours, eg \(18 \div 60\ (= 0.3)\) or \(78 \div 60\ (= 1.3)\) or for a correct process to convert speed in miles per minute to mph eg \(\text{``}0.833..\text{''} \times 60\) | |
| P1 | for using speed = distance ÷ time eg, \(65 \div [\text{time}]\) or \(65 \div 78\ (= 0.833..)\) | |
| A1 | cao | |
| SC B2 for 83(.333…) seen as the answer |
