-30% answer is right because it lost 3 inches and 30 percent of 10 is 3.
Answer: -30%
Equations:
100 + 35m
50 + 35m
Steps:
100 + 35m = 50 + 35m <span>
<em>Set the equations equal to each other.</em>
</span> <span />
<span>
100 + 35m = 50 + 35m <span>
-50 - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.
50+35m=35m
-35m -35m
<em>Subtract 35m from both sides of equation.</em>
50=m

The rate at which the sound travels in km/hr is 0.142km/hr
<h3>Conversion of m/s to km/hr</h3>
If a sound wave travels with a speed of 5120m/s, in order to convert to km/he, we will use the conversion factor below;
1hr = 3600secs
1km = 1000m
Using the conversion factor in our dimensional analysis
5120m/s = 5120m/1s * 1km/1000m * 3600s/1hr
5120m/s = 5120m/3600000
5120m/s = 0.142km/hr
Hence the rate at which the sound travels in km/hr is 0.142km/hr
