Question

On a map whose scale is 1 in = 110 ft, how far apart (in inches) would 4-ft contours be on a uniform slop of 3.2%

Answer 1

On a map with a scale of 1 in = 110 ft, 4-ft contours would be 4/110 inch apart.

Step-by-step explanation:

To determine the distance apart in inches of 4-ft contours on a map with a scale of 1 in = 110 ft, we need to find out how many inches represent 4 ft on the map. Since 1 inch on the map represents 110 ft, we can set up a proportion as follows:

1 inch / 110 ft = x inches / 4 ft

To solve for x, we can cross-multiply:

x = (1 inch / 110 ft) * 4 ft

x = 4/110 inch

Therefore, 4-ft contours would be 4/110 inch apart on the map.
