Answer:
Three, but see below.
Explanation:
You can be certain of three, but that may not be true at all. The only way to know for certain is to put it into scientific notation.
4.05 * 10^5 would be three, but other answers are possible. For example
4.050 * 10^5 would have 4.
Answer:
Δt = 0.315s
Explanation:
To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:


d1: distance to the first fan = 18.3 m
d2: distance to the second fan = 127 m
vs: speed of sound = 345 m/s
You replace the values of the parameters to calculate t1 and t2:

The difference in time will be:

Hence, the time difference between hearing the sound at the location s of both fans is 0.315s
