Question

The time between lightning flash and the following thunderclap may be used to estimate, in kilometers, how far away a storm is. How far way is a storm if 9 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. 27 kilometers
b. 18 kilometers
c. 12 kilometers
d. 3 kilometers

(I think the answer is d but I'm unsure, please help!)

Answer 1

9/3 is 3, so D is the correct answer

Answer 2

Answer: D. 3 kilometers

Explanation:

Here, the given formula, that shows the distance of storm,

`d=(t)/(3)`

Where, t is is the time, in seconds, between the flash and the thunderclap,

Here, t = 9 seconds,

Thus, the distance of the storm ,

`d=(9)/(3)=3\text{ km}`

Hence, the storm is 3 km away if 9 seconds elapse between the lightning and the thunderclap.
