A hybrid car averages 606 miles on a 12.5 gallon tank of gas. Manuel is planning a 1260-mile vacation in his hybrid car, how many gallons of gas he can expect to burt Manuel needs approximately gallons of gas for his vacation?
Manuel needs approximately 26 gallons of gas for his vacation.
Find the hybrid car's "mpg" -- (miles per each 1 gallon)
This can be solved as a Ratio&Proportion problem
Solve for m (miles)
606 ÷ 12.5 = 48.48
This result means that the hybrid car gets about 48.5 mpg
Find how many gallons to go 1260 miles
1260 miles @ 48.5 miles per gallon needs about 26 gallons
Check by estimating
The car uses about 12 gallons to go about 600 miles
The vacation will travel about 1200 miles -- double the miles given.
So the gallons of gas should double too -- to 24 gallons.
The actual answer is close to the estimate, so it is probably right.
