Suppose you hear a clap of thunder 7.20 s after seeing the associated lightning strike. The speed of light in air is 3.00 ✕ 108 m/s.

(a) How far are you from the lightning strike? (The speed of sound waves in air is 343 m/s.)
 km

(b) Do you need to know the value of the speed of light to answer?
    

Explain.

Suppose that you hear a clap of thunder 17.0 s after seeing the associated lightning stroke. The speed of sound waves in air is 343 m/s and the speed of light in air is 3.00 multiplied by 108 m/s. How far are you from the lightning stroke?

Suppose you hear a clap of thunder 16.2 s after seeing the associated lightning stroke. The speed of light in air is 3.00 × 108 m/s.
