Abody has a velocity of 72 km/hr. find its value in m/s.

If the body has a velocity of then its value in m/s is  .

Explanation:

To solve this we need to convert units.

means that the body travels 72 kilometers per hour. The prefix kilo indicates 10⁻³ or 1000. So we multiply 72 by 1000 and we get that 72 km=72000 m. Also 1 hour is the same as 3600 seconds.

Then we replace these values:
