✅ Answer: Yes, you are more likely to hear an echo on a hotter day.
Explanation:
The speed of sound increases with temperature because warmer air has more energetic molecules, which transmit sound waves faster.

On a hotter day, sound travels faster, which means the echo returns sooner.

However, the minimum time interval required to hear a distinct echo is 0.1 seconds, which corresponds to a minimum distance of about 17.2 meters (since echo must travel to and from the surface).

If the distance between the source and the reflecting surface remains the same:

On a hotter day, sound travels faster → the echo returns sooner → still heard if time gap ≥ 0.1 s.

So, if the distance is sufficient, you will hear the echo — possibly even more clearly due to faster sound propagation.

📌 Final Point:
Yes, you hear an echo on a hotter day, assuming the distance is enough for the echo time to be at least 0.1 seconds.
