Answer:
[tex]\approx 2\ miles[/tex]
Step-by-step explanation:
Difference of 10 seconds between the lightning flash and its thunder clap.
Given that the speed of light is infinite.
So, lightning will be seen at the same time it happens.
10 seconds is the time taken by the sound to reach to the person.
Time taken = 10 seconds
Speed of sound = 1080 ft/sec
To find:
Distance from lightning flash in miles.
Solution:
First of all, let us a have a look at the formula:
[tex]Distance = Speed \times Time[/tex]
Putting the given values:
Distance = [tex]1080\times 10 = 108000\ feet[/tex]
5280 feet = 1 mile
1 feet = [tex]\frac{1}{5280}[/tex] miles
10800 feet = [tex]\frac{1}{5280}\times 10800 \approx 2\ miles[/tex]
