C) because a new substance is formed
B) not sure but might be because the chemical properties of the substance has changed
We know that:
1 mile = 1.61 km
1 gal = 3.8 L
Therefore converting the fuel efficiency rates:
highway = (28.5 km/L) * (1 mile / 1.61 km) * (3.8 L / 1
gal) = 67.27 mile / gal
<span>city = (22.0 km/L) * (1 mile / 1.61 km) * (3.8 L / 1 gal)
= 51.93 mile / gal</span>
