correct answer is 373
the answer is wrong
the velocity of sound varies directly with the square root of its absolute temperature
V1/√T1 = V2/√T2
Multiplying both sides by √T2
V2 = V1 √T2/√T1
convert temperature to kelvin
temp in Celsius+ 273 = temp in kelvin
V2 = 354 * √320/288
V2 = 354 * √1.1111
V2 = 373 ms·¹
