After passing an obstruction while hiking, you need to turn left for a compass heading of 24 degrees. How far should you walk before turning again?

In navigational practices, especially in scenarios like hiking, maintaining an accurate sense of direction after passing an obstruction is crucial for ensuring you stay on track. When you've passed an obstruction and need to turn left to a compass heading of 24 degrees, it's important to establish a clear distance to walk before making another turn.

Walking a distance of 100 feet allows you to effectively orient yourself in the new direction while ensuring that you have a sufficient margin to reassess your surroundings and confirm that you are indeed proceeding along the intended path. This distance provides enough space to adjust your course without overly complicating navigation, helping to minimize potential errors that can occur with shorter distances, which may lead to losing orientation.

Choosing a distance that allows for clear directional sweeping and confirming landmarks is key, and 100 feet strikes a reasonable balance between distance and ease of navigation, thus making it the correct choice in this scenario.
