The velocity of sound in a gas is directly proportional to the square root of its absolute temperature (as v=√(ρ R T/M) ). Since, temperature of a hot day is more than cold winter day, therefore saved would travel faster on hot summer day than on a cold winter day.

Reason Velocity of sound is directly proportional to the square of its absolute temperature.

If both the assertion and reason are true and reason explains the assertion.

If both the assertion and reason are true but reason does not explain the assertion.

If assertion is true but reason is false.

If assertion is false but reason is true.

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