Respuesta :
The speed of light is much faster than sound. The storm is 2380 m far from Johnny.
Speed:
Speed is defined as the ratio of distance traveled by an object and time. It is measured in m/s. The formula of speed is,
[tex]\bold{Speed = \frac{Distance}{Time}}[/tex]
Given here,
The time taken by storm to reach Johnny = 7 sec.
The speed of sound = 340 m/s
Distance of storm =?
Put the values in the formula,
[tex]\bold{340 =\frac{Distance}{7} }[/tex]
Solve the equation for Distance,
Distance = 2380 m = 2.38 km
Therefore, the storm is 2380 m far from Johnny.
