Question

Passe para km,kg e s,responda:

a) 200m

b)3005g

c) 23h

Answer 1

$\boxed{\boxed{Ola\´ \: \: Vitoria}} }$

Aplicando a regra de três simples:

$\textbf{a)} \: 200m$

$1km ----- 1000 m \\ \: \: \: x ---- - - 200m \\ \Leftrightarrow x = \frac{200 \cancel{m} \cdot 1km}{1000 \cancel{m} } \\ \Leftrightarrow x = \frac{2 \cancel{0} \cancel{0} km}{10\cancel{0}\cancel{0} }$

$\Leftrightarrow \boxed{\boxed{x = 0,2km } }} \end{array}\qquad\checkmark$

$\textbf{b)} \: 3005g$

$1kg ----- 1000 g \\ \: \: \: y ---- - - 3005g \\ \Leftrightarrow y = \frac{3005 \cancel{g} \cdot 1kg}{1000 \cancel{g} }$
$\Leftrightarrow \boxed{\boxed{y = 3,005kg } }} \end{array}\qquad\checkmark$

$\textbf{c)} \: 23h$

$1h ----- 3600s \\ 23h ----- z \\ \Leftrightarrow z = \frac{23 \cancel{h} \cdot 3600s}{1 \cancel{h} }$
$\Leftrightarrow \boxed{\boxed{z = 82800s} }} \end{array}\qquad\checkmark$

Bons estudos!!
