Physics · Secondary 4 · Hard · Distance–time graphs

A jogger’s distance–time graph shows that her distance from the start increases from 0 m to 40 m between 0 s and 4 s, then stays at 40 m from 4 s to 8 s. What is her speed between 0 s and 4 s?

$10\text{ m/s}$
$5\text{ m/s}$
$0\text{ m/s}$
$0.25\text{ m/s}$
