Higher June 2024 Paper 2 Q8
8 A lion is sprinting in a straight line away from its den.
The graph shows the lion’s distance from the den.
Work out the speed of the lion in metres per second. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| A change in distance for an integer time interval or a change in distance for a non-integer time interval with the corresponding time interval | M1 | integer time intervals are [88, 92] [70, 74] [52, 56] [34, 38] [16, 20] may be seen on graph |
| \(\dfrac{\text{their change in distance}}{\text{corresponding time interval}}\) | M1dep | oe eg \(\dfrac{[88, 92]}{5}\) must see their change in distance and the corresponding time interval division by 1 may be implied |
| 18 | A1 | SC1 24 |
Additional guidance
| M1 may be awarded for correct work with no answer or incorrect answer, even if this is seen amongst multiple attempts | |
| \(90 \times 5\) | M1M0 |
| (1 second) Answer [16, 20] is awarded at least M2 | |
| 18 from incorrect working cannot score A1 | |
| 18 followed by further work eg \(18 \div 5 = 3.6\) | M1M0 |
