Question

A scale on a map reads 3 inches = 50 miles. Find the length on a map if the actual distance is 250 miles.

A. 15 inches
B. 12 inches
C. 10 inches
D. 5 inches

Answer 1

To find the length on the map if the actual distance is 250 miles, set up a proportion using the given scale of 3 inches = 50 miles. Solve for the unknown length on the map by cross-multiplying and dividing. The correct answer is 15 inches.

Step-by-step explanation:

To find the length on the map, we can set up a proportion using the scale. The given scale is 3 inches = 50 miles. We can write this as:

3 inches / 50 miles = x inches / 250 miles

Cross-multiplying, we get:

3 * 250 = 50 * x

750 = 50x

Dividing both sides by 50, we find:

x = 15

Therefore, the length on the map is 15 inches, so the correct answer is A. 15 inches.
