Question

PLEASE HELP!!!


Thunder is a sound wave created

by a lightning strike. If it travels at

343 m/s, how much time does it

take to travel a mile (1610 m)?

(Unit = s)

Answer 1

Answer:

t = 9.38 s

Explanation:

Given that,

The speed of the sound wave, v = 343 m/s

Distance, d = 1610 m

We need to find the time taken to travel a mile. The distance traveled by the sound is 2d. Using the formula for speed,

$v=\dfrac{2d}{t}$

t is the time taken to travel a mile

So,

$t=\dfrac{2d}{v}\\\\t=\dfrac{2\times 1610}{343}\\\\t=9.38\ s$

So, it will take 9.38 seconds.

Answer 2

Answer:

4.69s

Explanation:

The formula to find time is time = distance / velocity

Plug the numbers into the formula

So

1610 / 343

= 4.69s
