Un coche y una moto parten del mismo punto con la misma dirección y sentido al mismo tiempo. Calcula la distancia, en presas, entre los dos cuando han pasado dos horas, si la velocidad del coche es de 72 km / hy la velocidad del moto es de 25 m / s.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
