Answer: [tex]Ely, Chris, Jim, Dory[/tex]
Step-by-step explanation:
The distances must be expressed in the same uni.
Let's express the distance in meters.
We know that Dory lives 2.5 miles from school.
Since:
[tex]1\ mi = 1.61\ km[/tex]
The distance in kilometers is:
[tex](2.5\ mi)(\frac{1.61\ km}{1\ mi})=4.025\ km[/tex]
Since [tex]1\ km = 1,000\ m[/tex]
The distance in meters is:
[tex](4.025\ km)(\frac{1,000\ m}{1\ km})=4,025\ m[/tex]
Jim lives 3.2 kilometers from school. The distance in meters is:
[tex](3.2\ km)(\frac{1,000\ m}{1\ km})=3,200\ m[/tex]
Chris lives 3,000 yards from school.
Since:
[tex]1\ m = 1.09\ yd[/tex]
The distance in meters is:
[tex](3,000\ yd)(\frac{1\ m}{1.09\ yd})=2,752.29\ m[/tex]
Therefore, the order of the students from closest to farthest from school is:
[tex]Ely, Chris, Jim, Dory[/tex]
