Question

A hybrid car with a 9.80 gal tank consumes gasoline at a rate of 54.1 miles/gal. How many liters of gasoline will be consumed traveling 132 km?

Is my answer correct? Will show work in a post.

Answer 1

1 mile = 5280 ft
1 ft = 12 in
1 in = 2.54 cm
100 cm = 1 m
1000 m = 1 km

\[(\frac{ 54.1 miles }{ gal })(\frac{ 5280 ft }{ mile })(\frac{ 12 inches }{ ft })(\frac{ 2.54cm }{ inch })(\frac{ meter }{ 100cm })(\frac{ 132km }{ 1000m })(\frac{ 1gal }{ 3.78541 L})\]

= 3036.037674

since 54.1 is 3 significant figures =3040L

I got this wrong (on an online quiz) can you please tell me why.

Thanks in advance
