Sound travels at a speed of about 344 $\mathrm{m} / \mathrm{s}$ in air. You see a distant flash of lightning and hear the thunder arrive 7.5 seconds later. How many miles away was the lightning strike? (Assume the light takes essentially no time to reach you.)

Key Concepts

Speed of Sound

This concept refers to the rate at which sound waves propagate through different media. In air, under typical conditions, sound travels at about 344 meters per second, which serves as a benchmark value in many basic physics calculations.

Distance Calculation Using the Relationship between Speed and Time

The fundamental relation in kinematics, expressed as distance = speed × time, is used to determine how far a sound wave has traveled. When the time delay between an event (like lightning) and its subsequent sound (thunder) is known, this equation provides the distance between the event and the observer.

Unit Conversion

This involves converting numerical values from one set of units to another as required by the context of the problem. In this scenario, converting the distance from metric units (meters) to imperial units (miles) is necessary to provide an answer in the desired units.
