The speed of sound is 1236km/h.

Question

1. how many kilometers per minute is it?

Answer 1

To convert the speed of sound from kilometers per hour (km/h) to kilometers per minute (km/min), you can use the following conversion:

1 hour = 60 minutes.

So, to convert from kilometers per hour to kilometers per minute, you can divide the speed by 60.

Given the speed of sound is 1236 km/h:

\[ \frac{1236 \text{ km/h}}{60 \text{ min/h}} = 20.6 \text{ km/min} \]

Therefore, the speed of sound is approximately 20.6 kilometers per minute.
