To find the distance of the flash from the observer, we can use the relationship between the speed of sound and the time interval between the lightning flash and the first sound of thunder.
Here's how you can calculate it step by step:
1. Convert the time interval from seconds to milliseconds:
- The time interval is given as 5 seconds.
- Multiplying it by 1000 converts it to milliseconds.
- So, 5 seconds = 5000 milliseconds.
2. Use the formula speed = distance/time to find the distance:
- The formula for speed is given as speed = distance/time.
- The speed of sound in air is given as 330 meters per second (m/s).
- The time interval is given as 5000 milliseconds (ms).
Therefore, we can rearrange the formula to solve for distance:
distance = speed * time.
Plugging in the values, we get:
distance = 330 m/s * 5000 ms.
3. Convert the distance from meters to kilometers (optional):
- If you want the distance in kilometers, divide the distance by 1000.
- So, distance = (330 m/s * 5000 ms) / 1000.
4. Calculate the distance:
- Perform the multiplication and division in the equation:
distance = 330 * 5000 / 1000.
distance = 1650000 / 1000.
distance = 1650 meters.
So, the distance of the flash from the observer is 1650 meters.
