Question

A truck's odometer reads 69,189.7  at the beginning of a trip and 69,476.7  at the end. If the trip takes 14.1  gallons of gas, what is the gas mileage in miles per gallon? (Round to the nearest tenth)

anikhalder · Answer

No of miles travelled= 69476.7-69189.7=287 miles
Gas consumed=14.1 gallons
Hence,
On 14.1 gallons a trip of 287 miles is made
On 1 gallon a trip of 287/14.1= 20.35 miles/gallon
To the nearest tenth, the gas mileage is 20.4 miles/gallon
