Answer:

The equation would answer the question by substituting the time with 4.5 or d = 55(4.5) which is 247.5 miles. 

Using the table, 4.5 is halfway between 4 and 5 so the distance is between 220 and 275, or 247.5 miles. 

Therefore, the equation and the table both would give the same answer.

The graph is a little more difficult because I would need to draw a vertical line at the midpoint of 4 and 5 to the graphed line then follow it horizontally to the y axis.

This would give an approximate value of 250 miles, which is not as exact as the equation or the table.
