Taking into account the rule of three, the total distance that Ms. Wilson walked in 4 days is 3 miles.
Rule of three
In first place, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{cxb}{a}[/tex]
Total distance that Ms. Wilson walked
You can applied the following rule of three: if each day last week, Ms. Wilson walked [tex]\frac{3}{4}[/tex] mile, in 4 days what is the total distance that Ms. Wilson walked?
[tex]total distance=\frac{4 daysx\frac{3}{4} miles }{1 day}[/tex]
total distance= 3 miles
Finally, the total distance that Ms. Wilson walked in 4 days is 3 miles.
