Final answer:
The slope of the line representing the relationship between Peter's time and distance is the velocity which is 110 meters per minute.
Step-by-step explanation:
The slope of the line representing the relationship between Peter's time and distance is the velocity.
In this case, the velocity is equal to the distance travelled divided by the time taken.
The slope of the line can be calculated by finding the change in distance divided by the change in time.
In this case, the change in distance is 330 meters and the change in time is 3 minutes.
So, the slope of the line is 330/3 = 110 meters per minute.
