Spatial Reasoning Flashcards

A route map shows meters labeled A through E placed on alternating sides of the street. Meter A is on the left, B on the right, C on the left. Where is meter D?

Answer: Right side

The alternating pattern is left, right, left, right — so meter D follows meter C (left) and must be on the right side.

A meter reader's handheld device shows a meter location symbol 3 blocks ahead and 1 block to the left. Starting from their current position, what is the minimum number of blocks they must walk?

Answer: 4

The minimum path is 3 blocks forward plus 1 block left = 4 blocks total, assuming a standard grid with no shortcuts.

Which of the following correctly describes the relationship between a street map's scale and actual distance?

Answer: 1 inch on the map equals the same number of feet as the stated scale ratio

A map scale directly relates map distances to real-world distances — if the scale is 1 inch = 1,000 feet, then measuring 1 inch on the map means 1,000 feet in reality.

A meter reader must read meters on both sides of Main Street from 1st to 10th Avenue. To minimize backtracking, the most efficient approach is to:

Answer: Read left side going east, then right side going west

Reading one side going east and the other side going west (a boustrophedon or S-curve pattern) eliminates backtracking and is the standard efficient field approach.

On a map, a meter reader's current location is marked with a star. The next meter is 2 inches northeast on a 1 inch = 500 feet scale map. What is the approximate straight-line distance in feet?

Answer: 1,000 feet

Two inches on a 1 inch = 500 feet map equals 1,000 feet of straight-line distance (2 × 500 = 1,000 feet).

A meter is described as being 'behind the second house on the north side of Maple Street.' Which of the following diagrams best helps a reader find it?

Answer: A street map showing house positions and north arrow

A street map with house positions and a north direction indicator allows the reader to visually locate the second house on the north side and identify the backyard meter location.
