Q. A scale on a hiking map shows that 1.5 inches represents 4 miles.What number of actual miles are represented by 6 inches on the map?miles
Set Up Proportion: To find out how many actual miles are represented by 6 inches on the map, we need to set up a proportion based on the scale given. The scale tells us that 1.5 inches represents 4 miles. We can write this as a ratio: 1.5 inches / 4 miles. We want to find out how many miles correspond to 6 inches, so we set up the proportion rac{1.5 \text{ inches}}{4 \text{ miles}} = rac{6 \text{ inches}}{x \text{ miles}}, where x is the number of miles we're trying to find.
Cross-Multiply: Next, we solve for x by cross-multiplying. This means we multiply 1.5 by x and 4 by 6, and then set the two products equal to each other: 1.5×x=4×6.
Perform Multiplication: Now we perform the multiplication on the right side of the equation: 4×6=24. So our equation now is 1.5×x=24.
Divide Equations: To solve for x, we divide both sides of the equation by 1.5: x=1.524.
Calculate Final Result: Performing the division gives us the value of x: x=1.524=16. This means that 6 inches on the map represents 16 actual miles.
