Answer
0.5 seconds

The correct answer is 0.5 seconds — Thus the sound takes 0.5 seconds to travel 170 meters.

Step-by-step solution

  1. Use the formula time = distance ÷ speed.
  2. Distance = 170 m, Speed = 340 m/s.
  3. Time = 170 ÷ 340 = 0.5 s.
  4. Thus the sound takes 0.5 seconds to travel 170 meters.
Common mistake: Using the wrong formula (speed = distance × time)

Concept tested: Time–distance relationship
