Me. Deacons car travels 38 miles on a gallon of gas. Estimate the number of miles her car can travel on 7 gallons of gas.

Answer 1

In order to estimate how far the car can go with just 7 gallons of gas, you need to use the given information on how far the car goes with a specified amount of gas. => (38 miles with 1 gallon)

The first step is to find the average amount used with the specified info, which will be in the form of miles per gallon (miles / gallon). => (38 miles / 1 gallon) = 38 miles/gallon

Then with that average, you can find the answer by multiplying the number of gallons that you want to estimate for (7 gallons) which will cancel the gallon term in the average: Estimated Miles = (miles / gallon)*(Specified Gallons)

Estimated Miles = (38 miles/gallon)*(7 gallons) = 266 miles
