Question

A person yells at a canyon wall 200 m away. How long after they yell will they hear their echo

Answer 1

Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Explanation:Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Time = distance / speed

Time = 400 / 346

Time = 1.16 seconds

Answer 2

Assuming the air in the canyon is at 25 °C, the speed of sound is 346 m/s.

Total distance to be covered = 200 + 200 = 400 m

Time = distance / speed
Time = 400 / 346
Time = 1.16 seconds
