Question

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 1

Answer:

Given,

Time spent in fencing = 4 hours,

Length fenced in each hour = $\frac{1}{6}$ 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.

Answer 2

Answer:

Step-by-step explanation:

Given,

Time spent in fencing = 4 hours,

Length fenced in each hour =  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.
