Given - Distance 40 km
Speed - 340 m/s
Find - Time taken
Solution - Time taken for sound from explosion to reach the person can be calculated by the formula speed = distance /time.
To calculate the time, firstly units have to be converted to same units.
So, converting distance from kilometre to metre.
Distance = 40*1000
Distance = 40000 metres.
Now, calculating time.
Time = 40000/340
Time = 117.64 seconds.
Hence, the time taken will be 117.64 seconds.
