Complete Question
Angel runs 4 miles per Day. What Is the relationship between the Number of days and how many miles he has run? Is it proportional or non proportional?
Answer:
a) What Is the relationship between the Number of days and how many miles he has run?
The relationship between the number of days and how many miles he has run is as the number of days increases the number of miles he had run increases.
b) Is it proportional or non proportional?
Yes the number of days is DIRECTLY PROPORTIONAL to how many miles he has run
Explanation:
The question has proportionality involved.
Proportion or Proportionality had to do with two quantities that vary with each other.
The two quantities are Number of days and Number of miles
We can say:
Number of days ∝ Number of miles
Number of days = k × Number of miles
Where k is constant if Proportionality.
Angel runs 4 miles per Day.
Mathematically, this is expressed as:
1 days = k × 4 miles
k = 1/4
Let find the number of miles he had run in 2 days.
Number of days = k × Number of miles
2 = 1/4 × number of miles
Number of miles = 4 × 2
= 8 miles.
a) What Is the relationship between the Number of days and how many miles he has run?
The relationship between the number of days and how many miles he has run is as the number of day increases the number of miles he had run increases.
b) Is it proportional or non proportional
Based on the calculation above, where:
Number of days ∝ Number of miles
Yes, it is proportional and Number of days is DIRECTLY PROPORTIONAL to Number of miles Angel runs.
