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
