The formula for speed is distance divided by time. 300/25=12. Therefore, the average speed is 12 meters per second.
Answer:
The equation of the regression line is: 
Step-by-step explanation:
Linear regression is a linear approach to modelling the relationship between a dependent variable and one or more independent variables.
Let X be the independent variable and Y be the dependent variable. We will define a linear relationship between these two variables as follows:

We have the the following data:
