Asked by joe

A student witnesses a flash of lightning and then t = 6.5 s later the student hears the associated clap of thunder. Light travels at 3.0 × 108 m/s in the air. How long, t1, in seconds did it take the light to reach the student's eyes after the flash?

First, find the speed of sound, and then recall that

distance = time * speed.

Then, since time = distance/speed, divide that distance by the speed of light.
