The speed of sound is 1236 km/h. How many kilometers per minute is it?
The Correct Answer and Explanation is:
To convert the speed of sound from kilometers per hour (km/h) to kilometers per minute (km/min), we need to break down the calculation in a simple way.
We know:
- The speed of sound = 1236 km/h.
- 1 hour = 60 minutes.
To find the speed in kilometers per minute, divide the speed in kilometers per hour by the number of minutes in an hour:Speed in km/min=Speed in km/hMinutes per hour\text{Speed in km/min} = \frac{\text{Speed in km/h}}{\text{Minutes per hour}}Speed in km/min=Minutes per hourSpeed in km/h
Substituting the values:Speed in km/min=1236 km/h60 minutes/hour\text{Speed in km/min} = \frac{1236 \text{ km/h}}{60 \text{ minutes/hour}}Speed in km/min=60 minutes/hour1236 km/hSpeed in km/min=20.6 km/min\text{Speed in km/min} = 20.6 \text{ km/min}Speed in km/min=20.6 km/min
Thus, the speed of sound is 20.6 kilometers per minute.
Explanation:
The key concept here is that 1 hour consists of 60 minutes. So, by dividing the speed in kilometers per hour by 60, we convert it to kilometers per minute. This type of unit conversion is commonly used in physics, engineering, and various scientific fields when comparing different units of time. It’s a simple division problem where we take the total distance traveled in one hour and spread it out over the 60 minutes in that hour.
This result of 20.6 km/min represents the distance the sound would travel in one minute, assuming it’s traveling at the speed of sound in air at standard conditions (temperature and pressure).
