Detailed Solution

The velocity of sound in a gas is directly proportional to the square root of its absolute temperature $(as v = \sqrt{\frac{γRT}{M}})$ . Since temperature of a hot day is more than cold winter day, therefore sound would travel faster on a hot summer day than on a cold winter day.
