Answer:
2440 m
Step-by-step explanation:
The speed of light in air is approximately 3×10⁸ m/s.
The speed of sound in air at 28°C is approximately:
v = 331.4 m/s + 0.6 m/s/°C (28°C)
v = 348.2 m/s
Let's say the distance between you and the storm is x.
Distance = speed × time
x = 3×10⁸ t₁
x = 348.2 t₂
Since t₂ = t₁ + 7:
x / 348.2 = x / 3×10⁸ + 7
Solving for x:
x (1/348.2 − 1/(3×10⁸)) = 7
x = 2440
The storm is approximately 2440 meters away (round as needed).
