A Toyota Hillux Diesel has a fuel consumption of 9L/100 Km.

Question

How much fuel will it use to travel 375Km?

Answer 1

This question is asking about ratios—if it takes 9L to go 100km, it will take exactly 3.75x more gas to go 3.75x the distance (375km). Specifically, that means 9L· 3.75 = 33.75L.

Answer 2

Hello, Sarah,

We can use the fuel consumption as a conversion factor. We know that it requires 9 Liters to go 100 Km. I'll write that as

9L/100km, or 0.09L/km

We can use either as a conversion factor, but I'll chose 0.09L/km, because it helps make clear what we are doing.

Multiply it times the km we want to travel, which is 375km.

375km*(0.09L/km) = 33.8 liters. Note how km cancel, leaving just liters.
