Answer: Length of each part of his journey is
[tex]\frac{1}{48}\ miles[/tex]
Explanation:
Since we have given that
Tortoise must walk run [tex]\frac{1}{12}[/tex] miles to visit a friend.
According to question,
He plans to break a journey into four equal parts .
Length of each part becomes
[tex]\frac{\frac{1}{12}}{\frac{1}{4}}\\\\=\frac{1}{12\times 4}\\\\=\frac{1}{48}\ miles[/tex]
Hence, length of each part of his journey is
[tex]\frac{1}{48}\ miles[/tex]
