Answer:
a). Since the distance covered by Janie is 2 1/2 miles which is greater than 1 3/4 miles covered by Amir, we can conclude that Janie ran further than Amir.
b). Janie ran 3/4 miles further than Amir
c). d=J-A
Explanation:
Step 1: Determine distance covered by each runner
Amir=1 3/4 miles
Janie=2 1/2 miles
Step 2: Determine who ran further
Since the distance covered by Janie is 2 1/2 miles which is greater than 1 3/4 miles covered by Amir, we can conclude that Janie ran further than Amir.
Step 3: Write an equation to find d
The expression to find d is as follows;
d=J-A
where;
d=difference between the two distances
J=distance that Jane ran
A=distance that Amir ran
replacing'
d=(2 1/2-1 3/4)=(5/2)-(7/4)=3/4 miles
d=3/4 miles
Janie ran 3/4 miles further than Amir
