Question

How far away was a lightning strike if thunder is heard 7.20 seconds after the flash is seen? (Assume that sound traveled at 350.0m/s during the storm)

Answer 1

Answer: 2.52 Kilometers

Step-by-step explanation:

We know that the formula to calculate speed is given by :-

`\text{Speed}=\frac{\text{Distance}}{\text{Time}}\\\\\Rightarrow\text{Distance}=\text{Speed}*\text{Time}`

Given: The speed of sound during the storm :
`V=3350.0m/s`

The time taken by sound to travel :
`t= 7.20\text{ seconds}`

Then , the distance traveled by sound :-

`\text{Distance}=350*7.2=2520\text{ meters}=2.52\text{ kilometers}`
