Multiple choice

Assuming the speed of sound in air equal to $340 \ ms^{-1}$ and in water equal to $1360 \ ms^{-1}$, find the time taken to travel a distance $1700 \ m$ by sound in air

  1. $5\ s$
  2. $10 \ s$
  3. $2.5 \ s$

  4. None of the above

A Correct answer
Explanation

Time = Distance / Speed. Time = 1700 / 340 = 5 seconds.

AI explanation

Use the fundamental formula for time, which is time equals distance divided by speed. The required time is calculated as 1700 m divided by the given speed of sound in air, 340 m/s. This evaluates to 5 s.
