Answer:
D) y = 5x + 25
Step-by-step explanation:
the line of fit is defined by y = mx + b where:
m = the slope of the line (the rate of change)
b = the y-intercept (where it crosses the y-axis)
We see that for every 1 unit the graph moves horizontally... it moves 5 units vertically, thus we are given m = 5
If you look at the y-axis... we can determine that the graph crosses the y-axis at (0, 25), thus we are given b = 25
Therefore, the answer is y = 5x + 25
The average speed is the ratio between the distance covered, and the time elapsed to cover that distance.
The total distance is the sum of the three distances covered:

Similarly, the total time elapsed is

So, althought you didn't always travelled with the same speed, you globally covered 170km in 1.75 hours. This leads to an average speed of
