The bottom right.
The line best fit is usually the line that follows the trend of dots in the scatter plot. In the other 3, you can tell that there seems to be no trend between either the line or the dots.
The bottom right one has a line pretty much right through the middle of the scattered dots and follows the trend.

Answer:</h2>
- Trip to work has rate: 24 mph
- Trip back to home has rate: 18 mph
- Distance to work is: 480 m
<h2>
Step-by-step explanation:</h2>
We know that speed is defined as the ratio of distance to time.
i.e.
Let the distance traveled to work be: x m.
Now, while going to work it takes a person 20 minutes.
This means that the speed of the person while going to work is:
Also, the time taken to come back home is: 30 minutes.
This means that the speed of person while riding to home is:
Also, it is given that the rate back is 8 mph slower than the trip to work.
This means that:
i.e.
Hence, the distance to work is: 480 m.
Also, the rate while going to work is:
and the trip back to home is covered with the speed:
