A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}5120
Jet001 [13]

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

Convert the following in standard form : -4x=4y-52
goldenfox [79]
The standard form of any linear equation with two variables is ax+by=c, where a, b, and c are constants. To convert this equation to standard form, simply subtract 4y from both sides to get

-4x-4y=-52

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get

4x+4y=52
