[3] BC: constant speed 18 m/s for 50 s CD: deceleration 1.2 m/s² for 15 s
B1 for BC correct and B2 for CD completely correct or B1 for CD with one error or omission If 0 marks scored then SC1 for BC is constant speed and CD is deceleration
[2] 1215
M1 for ½ x 18 x(50 + 85) oe or one correct area: 180 or 900 or 135 or SC1 for answer 1080
