Si un submarino esta a - 83 metros a nivel del mar, sube a -15 cuantos metros subio?<br> ​
WITCHER [35]

Answer:

<em>El submarino subió 68 metros</em>

Step-by-step explanation:

<em>Desplazamiento</em>

Si un cuerpo cambia de posición desde X1 hasta X2, su cambio de posición se calcula como:

X=X2-X1

En el caso de nuestro submarino, su posición original era a X1=-83 m, luego sube a la posición X2=-15 m, así que su cambio de posición o desplazamiento es:

X=-15-(-83)=-15+83=68 m

El submarino subió 68 metros
