Q. A scale on a hiking map shows that 11.55 inches represents 44 miles.\newlineWhat number of actual miles are represented by 66 inches on the map?\newlinemiles
  1. Set Up Proportion: To find out how many actual miles are represented by 66 inches on the map, we need to set up a proportion based on the scale given. The scale tells us that 1.51.5 inches represents 44 miles. We can write this as a ratio: 1.51.5 inches / 44 miles. We want to find out how many miles correspond to 66 inches, so we set up the proportion rac{1.5 \text{ inches}}{4 \text{ miles}} = rac{6 \text{ inches}}{x \text{ miles}}, where xx is the number of miles we're trying to find.
  2. Cross-Multiply: Next, we solve for xx by cross-multiplying. This means we multiply 1.51.5 by xx and 44 by 66, and then set the two products equal to each other: 1.5×x=4×61.5 \times x = 4 \times 6.
  3. Perform Multiplication: Now we perform the multiplication on the right side of the equation: 4×6=244 \times 6 = 24. So our equation now is 1.5×x=241.5 \times x = 24.
  4. Divide Equations: To solve for xx, we divide both sides of the equation by 1.51.5: x=241.5x = \frac{24}{1.5}.
  5. Calculate Final Result: Performing the division gives us the value of xx: x=241.5=16x = \frac{24}{1.5} = 16. This means that 66 inches on the map represents 1616 actual miles.
