Higher June 2018 Paper 2 Q14
14 The distance-time graph shows information about part of a car journey.
Use the graph to estimate the speed of the car at time 5 seconds. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 11 – 19 | P1 | for drawing a tangent to the curve at time = 5 |
| P1 | for process to find the gradient, eg \(70 \div 5\) | |
| A1 | (dep on 1st P1) for answer in the range 11 - 19 m/s |
Additional guidance
Using their drawn tangent, eg change in \(y\) ÷ change in \(x\)
Must come from gradient of a tangent.
