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
