Question

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

Answer 1

The rate at which the sound travels in km/hr is 0.142km/hr

Conversion of m/s to km/hr

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
