Respuesta :

Recall that:

[tex]1\operatorname{km}=3280.84\text{ ft.}[/tex]

Therefore:

[tex]1ft=\frac{1}{3280.84}km\text{.}[/tex]

Multiplying the above by 62.95, we get:

[tex]\frac{62.95}{3280.84}km=0.01918715939\operatorname{km}\text{.}[/tex]

Now, since the initial number has 4 significant figures, we get that the conversion is:

[tex]0.01919km.[/tex]

Answer:

[tex]0.01919\text{ km.}[/tex]
