Question

Answer:

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]
