The distance between New York City and Los Angeles is approximately 2,450 miles. The speed of sound at sea level and at room temperature (20°C or 68°F) is about 767 miles per hour. To find out how long it would take to travel this distance at the speed of sound, we can use the formula:

Time = Distance / Speed

In this case:
