A man sets his watch by the noon whistle of a factory at a distance of 1.5 kilometres. By how many seconds is his watch slower than the clock of the factory? (Velocity of sound in air is 332 m/s.) (answer in $s$ ).
Answer:
4.52
Solution:
The sound takes $t = 1500/332 = 4.52$ s to reach him, so his watch is 4.52 s slow.
