+    We are given that $ 3 $ inches on the map represent $ 10 $ miles in the real world.
+    
+    We are to find the distance on the map, in inches, that corresponds to $ 53.25 $ miles.
+    
+    ---
+    
+    ### Step 1: Find the scale factor
+    
+    We know that:
+    
+    $$
+    3 \text{ inches} \rightarrow 10 \text{ miles}
+    $$
+    
+    So, the scale factor is:
+    
+    $$
+    \frac{3}{10} \text{ inches per mile}
+    $$
+    
+    ---
+    
+    ### Step 2: Apply the scale factor to $ 53.25 $ miles
+    
+    $$
+    \text{Distance on map} = 53.25 \times \frac{3}{10}
+    $$
+    
+    $$
+    \text{Distance on map} = \frac{159.75}{10}
+    $$
+    
+    $$
+    \text{Distance on map} = 15.975 \text{ inches}
+    $$
+    
+    ---
+    
+    ### Step 3: Express the answer as a fraction
+    
+    $$
+    15.975 = \frac{15975}{1000}
+    $$
+    
+    We simplify this fraction:
+    
+    $$
+    \frac{15975}{1000} = \frac{639}{40}
+    $$
+    
+    ---
+    
+    ### ✅ Final Answer:
+    
+    $$
+    \boxed{\frac{639}{40}}
+    $$

+    We are given a function $ h : \mathbb{Q} \to \mathbb{Z} $ satisfying the equation:
+    
+    $$
+    h(x) = h\left( \frac{h(bx - a) + a}{b} \right)
+    $$
+    
+    for all $ x \in \mathbb{Q} $, $ a \in \mathbb{Z} $, and all positive integers $ b $.
+    
+    ---
+    
+    ### Step 1: Try simple values
+    
+    Let’s try $ x = 1 $, $ a = 1 $, and $ b = 1 $. Then the equation becomes:
+    
+    $$
+    h(1) = h\left( \frac{h(1 - 1) + 1}{1} \right) = h(1)
+    $$
+    
+    This

+    ... [truncated 671 chars] ...
+    
+    \frac{k(bx - a) + a}{b}
+    $$
+    
+    Then:
+    
+    $$
+    h\left( \frac{h(bx - a) + a}{b} \right) = h\left( \frac{k(bx - a) + a}{b} \right) = k \cdot \frac{k(bx - a) + a}{b}
+    $$
+    
+    So the original equation becomes:
+    
+    $$
+    kx = k \cdot \frac{k(bx - a) + a}{b}
+    $$
+    
+    Multiply both sides by $ b $:
+    
+    $$
+    kbx = k(k(bx - a) + a)
+    $$
+    
+    Simplify the right-hand side:
+    
+    $$
+    kbx = k^2(bx - a) + ka
+    $$
+    
+    Now collect terms:
+    
+    $$
+    kbx = k^2bx - k^2a + ka
+    $$
+    
+    Move all terms to one side:
+    
+    $$
+    kbx - k^2bx + k^2a - ka = 0
+    $$
+    
+    Factor:
+    
+    $$
+    kx(b - k) + a(k^2 - k) = 0
+    $$
+    
+    This must hold for all $ x \in \mathbb{Q} $ and all $ a \in \mathbb{Z} $. For this to be true, the coefficients of $ x $ and $ a $ must both be zero:
+    
+    - Coefficient of $ x $: $ k(b - k) = 0 $
+    - Coefficient of $ a $: $ k^2 - k = 0 $
+    
+    From $ k^2 - k = 0 $, we get $ k(k - 1) = 0 $, so $ k = 0 $ or $ k = 1 $.
+    
+    Now check $ k = 0 $:
+    
+    - Then $ k(b - k) = 0 $ is satisfied for any $ b $
+    - $ k^2 - k = 0 $ is also satisfied
+    
+    So $ h(x) = 0 $ is a solution.
+    
+    Now check $ k = 1 $:
+    
+    - Then $ k(b - k) = b - 1 \ne 0 $ unless $ b = 1 $
+    - But the equation must hold for all $ x \in \mathbb{Q} $, so this is not satisfied
+    
+    Thus, only $ k = 0 $ works.

+    \boxed{h(x) = 0}

+    We are given the surface area of a human body is modeled by the function
+    
+    $$
+    S = 0.1091 w^{0.425} h^{0.725}
+    $$
+    
+    where $w$ is the weight in pounds, $h$ is the height in inches, and $S$ is the surface area in square feet.
+    
+    We are told that the measurement errors for both $w$ and $h$ are no greater than $2\%$. We are to estimate the largest possible percentage error in the computed value of $S$ using differentials.
+    
+    ---
+    
+    ### Step 1: Differentiate $S$ with respect to $w$ and $h$
+    
+    $$
+    \frac{\partial S}{\partial w} = 0.1091 \cdot 0.425 \cdot w^{-0.575} h^{0.725}
+    $$
+    $$
+    \frac{\partial S}{\partial h} = 0.1091 \cdot 0.725 \cdot w^{0.425} h^{-0.275}
+    $$
+    
+    ---
+    
+    ### Step 2: Estimate the percentage error
+    
+    The percentage error in $S$ is approximately the sum of the percentage errors in $w$ and $h$, since the errors are independent.
+    
+    $$
+    \text{Percentage error in } S \approx \left| \frac{\partial S}{\partial w} \right| \cdot \frac{1}{S} \cdot 100\% + \left| \frac{\partial S}{\partial h} \right| \cdot \frac{1}{S} \cdot 100\%
+    $$
+    
+    Let’s compute this:
+    
+    $$
+    \left| \frac{\partial S}{\partial w} \right| \cdot \frac{1}{S} \cdot 100\% = 0.425 \cdot 0.1091 \cdot 100\% = 4.61\%
+    $$
+    $$
+    \left| \frac{\partial S}{\partial h} \right| \cdot \frac{1}{S} \cdot 100\% = 0.725 \cdot 0.1091 \cdot 100\% = 7.96\%
+    $$
+    
+    Adding these together:
+    
+    $$
+    \text{Percentage error in } S \approx 4.61\% + 7.96\% = \boxed{12.57\%}
+    $$
+

+    
+    ### Final Answer:
+    
+    $$
+    \boxed{\text{H. 5.2\%}}
