Suppose you were told that the company built the fence 4 hours and that they completed 1\6 mile of the fence each hour. How would you use the double number line to help you find he length of the fence?

Answer:Given,Time spent in fencing = 4 hours,Length fenced in each hour = [tex]\frac{1}{6}[/tex] miles. We need to find : The length of the fence.By using the double number line to solve this problem,We will follow the following steps,Step 1 : Draw two straight parallel lines, first represents time in hours second represents length in miles.Step 2 : Make 4 tick marks in first line in which each mark represents each hour.Step 3 : Make corresponding 4 marks in second line.Step 4 : If first tick in second line represents 1/6 then it is obvious that last tick mark represents 4/6 or 2/3.Hence, the length of fence is 2/3 miles.
