A car averages 28.5 miles per gallon of gasoline. How many liters of gasoline will be needed for a trip of 415 km? Some conversi
GrogVix [38]

Answer:

34.22 liters

Step-by-step explanation:

Step one:

Given data

A car averages 28.5 miles per gallon of gasoline

How many liters of gasoline will be needed for a trip of 415 km

let us convert 415km to miles first

1 km is 0.621371 miles

415km is x miles

cross multiply we have

x= 415*0.621371

x=257.86 miles

Step two:

if 1 gallon of gasoline will cover 28.5 miles

the x gallons will cover 257.86 miles

cross multiply we have

28.5x= 257.86

divide both sides by 28.5

x= 257.86/28.5

x=9.04 gallons

Step three:

let us convert gallons to liters

1 gallon is 3.78541 liters

9.04 gallons will be x liters

cross multiply we have

x=9.04*3.78541

x= 34.22 liters
