A spoil pile must be 24 inches from a trench edge, but it is 7 inches away. How much farther back must it move?
Correct Answer
D) 17 inches.
The spoil pile must move 24 - 7 = 17 more inches.
Why This Is the Correct Answer
The spoil pile must move 24 - 7 = 17 more inches.
Why the Other Options Are Wrong
Option A: 7 inches.
7 inches. is below the supported result for excavation spoil; it likely drops a required step.
Option B: 24 inches.
24 inches. is above the supported result for excavation spoil; it likely adds a step the rule does not support.
Option C: 31 inches.
31 inches. is above the supported result for excavation spoil; it likely adds a step the rule does not support.
