Question

A Toyota Prius Hybrid uses 59.7 L gasoline to drive from San Francisco to Seattle, a distance of 1300 km (two significant digits). What (average) fuel economy, in miles per gallon, did the Prius get during this trip?

Answer 1

Average will be approx 51 mpg.

Explanation:

1 km = 0.6213 mile

So, 1300 km =
`1300*0.6213=807.69` miles

Given is - A Toyota Prius Hybrid uses 59.7 L gasoline to drive from San Francisco to Seattle, a distance of 1300 km or 807.69 miles.

1 L = 0.2641 gallons

So, 59.7 L =
`59.7*0.2641= 15.76` gallons

We can say that in 15.76 gallons the car drives 807.69 miles.

So, in 1 gallon, it drives
`(807.69)/(15.76)`=51.25 miles

Hence, the economy is 51.25 miles per gallon.

Average will be approx 51 mpg.
