To solve for the time it takes the tortoise to walk 1 mile, we start by expressing the given division as a multiplication expression.
We have:
\[ \frac{141}{65} \div \frac{65}{65} = \frac{141}{65} \cdot \frac{1}{65} \]
This multiplication simplifies to:
\[ \frac{141 \cdot 1}{65 \cdot 65} = \frac{141}{65^2} \]
However, we only want to find how long it takes for 1 mile. A more straightforward way to calculate the time for one mile is to first find the rate per mile.
We know the tortoise walks \( \frac{141}{65} \) hours to cover \( \frac{65}{65} = 1 \) mile.
Thus, we can set up the problem as follows:
- Calculate time per mile:
\[ \text{Time for 1 mile} = \frac{141}{65} \div \frac{65}{65} \]
This is effectively:
\[ \text{Time for 1 mile} = \frac{141}{65} \]
To compute this, you can do the division:
\[ 141 \div 65 \approx 2.1692 \]
Therefore, it takes approximately \( 2.1692 \) hours to walk 1 mile.
Summary:
- The tortoise takes \( \frac{141}{65} \) hours to walk 1 mile, which can be approximated to about \( 2.17 \) hours.
