Questions & Step-by-Step Solutions
If the speed of sound in air is 340 m/s, how long does it take for sound to travel 1 km?
Step 1: Understand that we need to find the time it takes for sound to travel a certain distance.
Step 2: Know the speed of sound in air, which is given as 340 meters per second (m/s).
Step 3: Convert the distance from kilometers to meters. Since 1 kilometer is equal to 1000 meters, we have a distance of 1000 meters.
Step 4: Use the formula for time, which is Time = Distance / Speed.
Step 5: Plug in the values: Time = 1000 meters / 340 meters per second.
Step 6: Calculate the time: 1000 / 340 = approximately 2.94 seconds.
Speed, Distance, and Time Relationship – This question tests the understanding of the relationship between speed, distance, and time, specifically how to calculate time using the formula time = distance/speed.
