Answer
20 miles are equal to 32 km.
Solution
To solve this problem, we need to set up a proportion using the given information that 10 miles is approximately equal to 16 km.
Let's denote the number of miles that is equal to 32 km as \( x \) miles.
We can set up the proportion as follows:
\[ \frac{10 \text{ miles}}{16 \text{ km}} = \frac{x \text{ miles}}{32 \text{ km}} \]
Now, we can solve for \( x \) by cross-multiplying:
\[ 10 \times 32 = 16 \times x \]
\[ 320 = 16x \]
\[ x = \frac{320}{16} \]
\[ x = 20 \]
Therefore, approximately 20 miles would be equal to 32 km.

To find out how many miles correspond to 32 km, we can set up a proportion based on the given equivalence of 10 miles to 16 km. First, let’s establish that 1 mile is approximately 1.6 km. So, to convert 32 km to miles, we can divide by 1.6: \[ 32 \text{ km} \div 1.6 \text{ km/mile} \approx 20 \text{ miles}. \] This means that approximately 20 miles is equal to 32 km. Now for your ratio question, you have: \[ \frac{5}{16 \text{ km}} \text{ miles } = \frac{? \text{ miles }}{92 \text{ km}} \] Using cross-multiplication: \[ 5 \times 92 = 16 \times ? \] \[ 460 = 16 \times ? \] \[ ? = \frac{460}{16} \approx 28.75. \] Thus, approximately 28.75 miles correspond to 92 km.
