Answer: B. 12,000 feet
Step-by-step explanation:
Given : The measure of Mary's stride= 2 feet, 8 inches.
We know that 1 feet =1 2 inches
Then, the measure of Mary's stride= [tex]2+\dfrac{8}{12}\ feet[/tex]
[tex]=\dfrac{12(2)+8}{12}=\dfrac{32}{12}\ feet[/tex]
No,. of steps = 4500
Then, Distance = No. of steps x Measure of Mary's stride
=[tex]4500\times\dfrac{32}{12}\\\\=375\times32=12000\ feet[/tex]
Hence, the distance she will walk if she takes 4,500 steps=12000 feet
Hence, the correct answer is B. 12,000 feet
