Use the image to answer the question.

An illustration shows quadrant one of a coordinate plane where the x-axis and y-axis range from 0 to 6 in increments of 1. The y-axis is titled distance in feet and the x-axis is titled time in seconds. A solid line, labeled A, is marked on the graph and passes through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 3 comma 6 right parenthesis. A dotted line, labeled B, is marked on the graph and passes through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 6 comma 6 right parenthesis. A dashed line, labeled C, is marked on the graph and passes through coordinates left parenthesis 0 comma 0 right parenthesis and left parenthesis 6 comma 3 right parenthesis.

To determine which object would reach 100 feet in the least amount of time, we need to analyze the slopes of the lines represented by each object.

  1. Object A: The line goes through the points (0, 0) and (3, 6), giving it a slope of 6/3 = 2 feet per second.

  2. Object B: The line goes through the points (0, 0) and (6, 6), resulting in a slope of 6/6 = 1 foot per second.

  3. Object C: The line goes through the points (0, 0) and (6, 3), providing a slope of 3/6 = 0.5 feet per second.

Now, let's calculate the time it takes each object to reach 100 feet.

  • For Object A: At a rate of 2 feet per second, it takes 100 feet / 2 feet per second = 50 seconds.
  • For Object B: At a rate of 1 foot per second, it takes 100 feet / 1 foot per second = 100 seconds.
  • For Object C: At a rate of 0.5 feet per second, it takes 100 feet / 0.5 feet per second = 200 seconds.

Thus, Object A reaches 100 feet in the least amount of time, which is 50 seconds.

Final answer: object A.
