✅ Correct.

The steps and calculations for determining the height of the tower using the echo method are accurate.

  1. The explanation of the echo method is correct, stating that the total distance covered by sound is twice the height of the tower due to reflection.

  2. The given values for the speed of sound (vs=340 m/sv_s = 340 \text{ m/s}) and time for echo (t=0.5 st = 0.5 \text{ s}) are correctly identified, and the formula 2H=vs×t2H = v_s \times t is correctly applied.

  3. The formula is correctly rearranged to solve for HH

    H=vs×t2H = \frac{v_s \times t}{2}

    And the substitution and calculation are correct:

    H=340 m/s×0.5 s2H = \frac{340 \text{ m/s} \times 0.5 \text{ s}}{2} H=170 m2H = \frac{170 \text{ m}}{2} H=85 mH = 85 \text{ m}

    The final answer 85 m\boxed{85 \text{ m}} is correct.
