Suppose you were told that the company built the fence in 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 the length of the fence?

Solution  :

It is given that the time required by a company to built the fencing = 4 hours

The length of fenced completed in 1 hour = 1.6 mile

Now by using the double number line to find the length of the fence, we would :

-- We have to draw two parallel straight lines.

-- Let the 1st line represents the time measured in hours and the 2nd line represents the distance or length measured in miles.

-- Mark four marks of equal spacing in both the line so that each mark represents 1 hour in the 1st line and each mark in the 2nd line represents the corresponding lengths.

-- Now in hour, they completed 1.6 miles, therefore from the double number line, we can see that in 4 hours, they completed 4.6 miles of fencing.

Hence the length is 4.6 miles.
