Using proportions, considering the ratio given in the double number line, it is found that there are 7.04 yards in 4 miles.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching the problem on the internet, it is found that there are 3.52 yards in 2 miles. Hence the following rule of three is used to find the number of yards in 4 miles.
2 miles - 3.52 yards
4 miles - n yards
Applying cross multiplication:
2n = 4 x 3.52
Simplifying by 2:
n = 2 x 3.52
n = 7.04 yards.
There are 7.04 yards in 4 miles.
