To the nearest tenth of a minute, how long would it take a sound wave to travel 20000 meters?

Question

on planet earth, sound waves travel through the air at a speed of 343 meters per second 

Answer 1

time = distance / speed

 

distance = 20000 m

speed = 343 m/s

 

Plug in the numbers and get time in seconds, then divide by 60 to get time in minutes.
