Velocity of sound in air is dependent on the absolute temperature of the medium in which it travels. It is proportional to square root of T.
v ∞ √T
T1 = 7°C = 280°K
T2 = ?
Given v2 / v1 = 1.5
v2/v1 = √(T2 / T1)
1.5² = T2/T1
T2 = 2.25 * T1
= 2.25 * 280 = 630°K
= 357°C
So at 357°C sound travels at 1.5 times the speed at 7°C.
