Sagot :

Answer:

[tex]45\,\,km/h[/tex]

Explanation:

Given: [tex]12.5\,\,m/s[/tex]

To express: [tex]12.5\,\,m/s[/tex] into [tex]km/h[/tex]

Solution:

Use the following relations between [tex]m[/tex] and [tex]km[/tex], [tex]s[/tex] and [tex]h[/tex]

Here, [tex]m[/tex] denotes meter, [tex]km[/tex] denotes kilometer, [tex]s[/tex] denotes seconds and [tex]h[/tex] denotes hour.

[tex]1\,\,m=\frac{1}{1000}\,\,km[/tex]

[tex]1\,\,s=\frac{1}{3600}\,\,h[/tex]

Therefore,

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