Eddie walks 450.25 feet in 2.5 minutes. Which value is closest to the number of yards Eddie walks in 1 minute?
1 answer:
Eddie walks 60.03 yards in 1 minute using proportion.
What is proportion?
The term proportionality refers to any relationship that has the same ratio every time. The proportional relationship between the two supplied ratios is defined by an equation. In other terms, the proportion declares that the two fractions or ratios are equal. For instance, the average number of apples per tree determines the proportionality between the quantity of apples in a crop and the number of trees in the orchard.
Here let us take time and distance as proportional values,
=>
=> 450.25/2.5 = x/1
=> x = 180.1 feet.
To convert feet to yards divide the length by 3. then
=> 180.1/3=60.03 yards,
Therefore Eddie Walks 60.03 yards in 1 minute.

Answer:
Day 21: 810 m
Day 60: 1,200 m
Step-by-step explanation:
The amount of meters she walk everyday can be modeled as a linear function, as the rate of variation is a constant (10 m/day):
This constant (10 m/day) is the slope of the linear function.
We know one point of the linear function (D(20)=800) and the slope, so we can calculate the y-intercept:
Now, we can calculate the distance she walks by day 21 and day 60:
