Question

A hybrid car averages 600 miles on a 12.9 gallon tank of gas. Manuel is planning a 1240-mile vacation in his hybrid car. Find how many gallons of gas he can expect to burn.

Answer 1

26.66 gallon of gas

Explanation:

A car uses 12.9 gallons of gas for travelling 600 miles

For travelling one mile , the car will use gas = 12.9 gallon of gas/600 miles

= 0.0215 gallon of gas /mile

For travelling 1240 miles, gallon of gas required =

= 0.0215 gallon of gas /mile x 1240 miles

= 26.66 gallon of gas

Answer 2

the average distance travelled by the car - 600 miles
amount of gas used up - 12.9 gallons
therefore when he travels 600 miles he uses up 12.9 gallons

for every mile the amount of gas used up - 12.9 gallons / 600 miles = 0.0215 gallons / mile
therefore 0.0215 gallons used up per mile

so when he's going for 1240 miles - gas used up is 0.0215 gallons/ mile x 1240 miles = 26.66 gallons

amount of gas needed is 26.66 gallons
