Tenemos que

R------------ > recorrido total
x---------------- > viaje en tren--------------- > (1/2)*R 
y----------------- > viaje en bicicleta-------------(1/2)*(1/3)*R=(1/6)*R
z------------------- > viaje en automovil --------- > (1/2)*(2/3)*R=(2/6)*R=100 km
R=x+y+z
resolviendo nos queda que
(2/6)*R=100--------------- > R=100*6/2=300 km
viaje en tren----------- > (1/2)*R=300/2=150 km
viaje en bicicleta------- > (1/6)*R=300/6=50 km
( estos dos ultimos calculos no lo estan pidiendo y no hacen falta para contestar la pregunta, simplemente se realizan a manera didactica)

La respuesta  es
La distancia entre las dos ciudades es de 300 km

What is the area of a regular nonagon (9 sides) with side length of 15 cm and apothem of 20.6 cm? Round the answer to the neares
Triss [41]
We know that

<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]

</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²

the answer is
1390.5 cm²
