Queremos encontrar una ecuación que relacione la <u>cantidad de combustible</u> que una locomotora consume con la distancia que esta recorre.

Veremos que:

a) 318.7 L

b) 796.8 L

c) 120.2 km

------------------------------

Veamos como resolver esto.

Primero, sabemos que la locomotora consume 39.9L para moverse una distancia de 10 km.

Entonces la cantidad que se mueve por litro es:

r  = (10 km)/(39.9 L) = 0.251 km/L

Así podemos escribir la ecuación:

D =  (0.251 km/L)*C

Donde D es una distancia y C es la <u>cantidad de combustible que se consume.</u>

a) ¿Cuántos  litros de diésel consumirá para mover la misma carga a 80 km?

Reemplazamos D por 80km y resolvemos para C:

80km =  (0.251 km/L)*C

80km/(0.251 km/L) = C = 318.7 L

b) ¿Cuántos  litros de diésel consumirá para mover la misma carga a 200 km?

Reemplazamos D por 200km y resolvemos para C:

200km =  (0.251 km/L)*C

200km/(0.251 km/L) = C = 796.8 L

c) Si ha consumido 478.8 litros, ¿qué distancia  ha recorrido?

Reemplazamos C por 478.8 L y resolvemos para D:

D = (0.251 km/L)*478.8 L = 120.2 km

The answer really depends on what b is. Unless you give me a number for what b equals I can’t solve it.
