The quantity of fuel consumed by the train is 400 litres.
In this question,
Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. If one quantity is increased or decreased then the other quantity increases or decreases, respectively.
A train consumes fuel = 1.5 litres
Distance covered by the train = 45km
Then for 1 km, quantity of fuel consumed by train = [tex]\frac{1.5}{45}[/tex]
Here, it follows the direct variation. As distance increases, quantity of fuel consumption also increases. Thus,
Quantity of fuel consumed by train for 1200km is
⇒ [tex]1200(\frac{1.5}{45} )[/tex]
⇒ 400 litres
Hence we can conclude that the quantity of fuel consumed by the train is 400 litres.
