Look at the distance-time graph for a runner's training session.
What is the average speed for the journey?
Use the equation: average speed=distance travelled÷time\text{average speed} = \text{distance travelled} \div \text{time}average speed=distance travelled÷time
0.25 m/s0.25\text{ m/s}0.25 m/s
4.0 m/s4.0\text{ m/s}4.0 m/s
3.75 m/s3.75\text{ m/s}3.75 m/s
40 m/s40\text{ m/s}40 m/s
