With the velocity of sound in aluminum approximately 245,000 inch/sec, how long does sound take to travel 1 inch?

Explanation:
Time equals distance divided by velocity. With sound in aluminum at about 245,000 inches per second, the time to cover 1 inch is t = 1 inch / 245,000 inches per second ≈ 4.1 × 10^-6 seconds, which is about 4 microseconds. That is why the 4 micro sec option fits. The other times are orders of magnitude larger, not matching the very rapid travel of sound in metal.
