Answer:

0.854miles away

Explanation:

The relationship between the speed of the sound (v), the distance between the sound of thunder and the reflector (x) and the time (t) can be expressed as 2x = vt

Given the speed of sound = 344m/s

time = 8.0s

x = ?

Substituting this values into the formula to get x, we have;

2x = 344(8)

x = 344×8/2

x = 1376m

Converting this distance to miles

0.000621miles = 1m

x = 1376m

x = 1376×0.000621

x = 0.854miles

The lightening strikes 0.854miles away.

Answer:

<em>The lighten travels 0.853 miles.</em>

Explanation:

Sound: Sound is a form of wave which is conveyed through an elastic medium from a vibrating body to a listener.

v = 2x/t .......................................... Equation 1

making x the subject of the equation

x = vt/2........................................ Equation 2

Where v = velocity of sound in air, x = distance traveled by the sound, t = time

Given: v = 344 m/s t = 8 s

Substituting into equation 2

x = 344(8)/2

x = 1376 m.

x = 1376×0.00062 miles = 0.853 miles

<em>Thus the lighten travels 0.853 miles.</em>
