Answer 2

Answer:

Average speed = 45 m/s.

Step-by-step explanation:

The average speed is the distance divided by the time. How do we get the distance? Get the area under the graph. Since it's a curved graph, it's more difficult to get nice shapes to calculate the area of. This is why the question asks you to estimate, no-one will sit there and count each tiny little square for the area. So we split the area under the graph into some shapes that we can calculate the area of. The more shapes you split the area into, the more accurate your answer will be.

Good luck, student!
