1)The velocity of sound in air is 332 m/s. If the unit of length is km and the unit of time is hour, what is the value of velocity?
m/s
bobpursley said he would be happy to check my work but I don't know what they're looking for I thought they are looking for the unit which is what I gave. what numbers do I use?
1195.2 m/s
It seems to me that it is looking for the value of speed in km/hr. Separate subject: How did you get 332m/s to equal 1195m/s ?
I have that same exact question I need to answer, but I'm not sure how to answer it because it's not in my text book. :( Help?
To find the value of velocity in m/s, you need to convert the given value of 332 m/s to the desired units of km/hour.
First, let's convert meters to kilometers:
1 kilometer = 1000 meters
To convert meters to kilometers, divide the given value by 1000:
332 m/s ÷ 1000 = 0.332 km/s
Now, let's convert seconds to hours:
1 hour = 3600 seconds
To convert seconds to hours, divide the value obtained from the previous step by 3600:
0.332 km/s ÷ 3600 = 0.00009222 km/h
Therefore, the value of velocity in km/hour is approximately 0.00009222 km/h.
