Interpret the gradient on a linear section on a real life graph Jadon decides to go for a run.
The graph on the right shows Jadon's speed in metres per second \( (s) \) over time in seconds
\( (t) \).

The gradient of the negative sloping section of the graph is \( 0.8 \).

Which of the following does that \( 0.8 \) best represent? ![A sketch of a graph with s on the y axis and t on the x axis. A straight line slopes upwards from the origin 2/3 of the way up the graph, 1/5 across the graph. It then becomes horizontal for the next 1/5 of the graph, before sloping downwards in a straight line for the remainder of the graph. ]() Jadon is accelerating at a rate of \( 0.8 \mathrm{~m} / \mathrm{s}^{2} \)

Believes a downward slope on a speed-time graph shows positive acceleration
