Answer:
Explanation:
To determine the actual length represented by a given length on a drawing, you need to use the scale ratio. In this case, the scale is 1 cm : 50 km. This means that 1 cm on the drawing represents 50 km in actual length.
To find the actual length represented by a length of 8.6 cm on the drawing, we can set up a proportion:
1 cm : 50 km = 8.6 cm : x
To solve for x, we can cross-multiply:
1 * x = 50 * 8.6
x = 430 km
Therefore, the actual length represented by a length of 8.6 cm on the drawing is 430 km.
