Question

12.5 m/s can be expressed into km/h​

Answer 1

Answer:

$45\,\,km/h$

Explanation:

Given: $12.5\,\,m/s$

To express: $12.5\,\,m/s$ into $km/h$

Solution:

Use the following relations between $m$ and $km$, $s$ and $h$

Here, $m$ denotes meter, $km$ denotes kilometer, $s$ denotes seconds and $h$ denotes hour.

$1\,\,m=\frac{1}{1000}\,\,km$

$1\,\,s=\frac{1}{3600}\,\,h$

Therefore,

$12.5\,\,m/s=\frac{12.5(3600)}{1000}=45\,\,km/h$
