At 20°C, the speed of sound propagates at 343 m/s.
If thunder was heard 3.00 seconds after the flash of lightning was observed, the storm was 343 * 3 = 1029 m (0.639390956811873 miles) distant.
For sake of comparison, the speed of sound at
0°C = 331 m/s the storm would be 993 m (0.617021593891341 miles)
25°C = 346 m/s the storm would be 1038 m (0.644983297542006 miles)

Temperature does not determine the distance of a storm.
To determine the distance of a storm, once lightning strikes, count the seconds until you hear the thunder then divide by five to estimate how many miles away the lightning strike was.
The storm would be 0.6 miles away.
