Answer: $11\frac{1}{8}\text{ inches}$ (Converted to common denominators: $\frac{2}{8} + \frac{3}{8} + \frac{4}{8} = \frac{9}{8} = 1\frac{1}{8}$, added to whole numbers $3 + 5 + 2 = 10$, total $11\frac{1}{8}$).
Question 2 (Algebra): Solve for $x$ in the equation: $3x – 5 = 16$.
Answer: $x = 7$ (Add $5$ to both sides to get $3x = 21$, then divide by $3$).
Question 3 (Ratios): If a pipe fitting requires a ratio of 3 parts solvent to 2 parts cleaner, how many ounces of solvent are needed for a total mixture of $20\text{ ounces}$?
Answer: $12\text{ ounces}$ (Total parts = $5$. Each part is $20 / 5 = 4\text{ ounces}$. Solvent = $3 \times 4 = 12$).
Question 4 (Mechanical Reasoning): If Gear A turns clockwise with 20 teeth and drives a smaller Gear B with 10 teeth, which direction does Gear B turn and at what speed relative to Gear A?
Answer: Gear B turns counter-clockwise at twice the speed of Gear A due to the 2:1 gear ratio.
