The time between a lightning flash and the following thunderclap may be used to estimate, in kilometers, how far away a storm is.How far away is a storm is 6 seconds elapse between the lightning and the thunderclap? Use the formula d=t/3,where t is the time,in seconds, between the flash and the thunderclap. A.18 kilometers B.2 kilometers C.3 kilometers D.9 kilometers what is the correct answer
The correct answer is D. 9 kilometers.
Using the formula d=t/3, where t=6 seconds, we get:
d = 6/3 = 2 kilometers per second
However, we need to convert this to kilometers per minute, since the distance is usually measured in kilometers per minute. To do this, we multiply by 60:
d = 2 x 60 = 120 kilometers per minute
Therefore, the storm is 9 kilometers away, since it takes 6 seconds for the sound to travel 2 kilometers and 1 minute (60 seconds) for the sound to travel 120 kilometers.
