Question

A velocidade escalar,em km/h se um ciclista que se desloca a 10m/s

Answer 1

$1\text{m}=\dfrac{1\text{km}}{1000}\qquad\qquad\qquad1s=\dfrac{1h}{3600}\\\\\\10\text{m}/\text{s}\Rightarrow\dfrac{10\,\text{m}}{\text{s}}\Rightarrow\dfrac{10\!\cdot\!\dfrac{\text{km}}{1000}}{\dfrac{h}{3600}}\Rightarrow\dfrac{\dfrac{\text{km}}{100}}{\dfrac{h}{3600}}\Rightarrow\dfrac{\text{km}}{100}\cdot\dfrac{3600}{h}\Rightarrow36\!\cdot\!\dfrac{\text{km}}{h}=\boxed{\boxed{36\text{km}/h}}$

Answer 2

10m/s        km/h=1000m      1h = 60x60=3600s     10 x 3600= 36000     36000/1000 =36     V 36Km/h
