An echo is heard when the time for the reflected sound is heard after 0.1sec.
The speed of sound in a medium increases with an increase in temperature. Hence, on hotter day the time interval between original and reflected sound will decrease.
Therefore, an echo can be heard only if the time interval between the original sound and the reflected sound is greater than 0.1s
