Question

Miranda was parking her car in a car park one day and couldn't tell how far forward she was so she decided to honk the horn and calculated the distance. She noticed the time it took for her to hear the reflected sound was 0.5 seconds. Find how far she was from the wall

Answer 1

Answer:

Speed of sound in air is 343 m/s

If sound returned in 0.5 s

it means half of 1

So wall is at 171.5 m far
