If on a winters day the return distance is the same 1727 and takes 5.50 s the speed is 1727/5.5 = 314 m/s and equals
331 0.6*tw
Therefore 314 = 331 0.6*tw
-17 = 0.6*tw
tw = -28.3 deg C
The speed of sound is given by the following formula:-
331 0.6*t metres/s
At 24 deg C speed is therefore 331 0.6*24 = 331 14.4 = 345.4m/s
If the echo takes 5.00 s to make the return trip the return distance is 345.4*5 = 1727m
If on a winters day the return distance is the same 1727 and takes 5.50 s the speed is 1727/5.5 = 314 m/s and equals
331 0.6*tw
Therefore 314 = 331 0.6*tw
-17 = 0.6*tw
tw = -28.3 deg C
