How many kilometers can the Prius travel on 13 liters of gasoline?
Express your answer using two significant figures.
Answer by Kristie
This assumes a mileage rating of 52 mpg (miles per gallon)
Using dimensional analysis
(52 miles/gallon)(1.61 km/mile)(1 gallon/3.78541 L) = 22.12 km/L
Using the converted mileage:
(22.12 km/L)(13 L) = 287.5 km
Answer to 2 significant figures is 290 km (or 2.9 x 10^2 km)
