If you traveled 226 miles during a 4 hour trip and used 10.5 gallons of gasoline, which expression tells you how many miles unto the gallon your car got on avarage

Sagot :

AL2006
"Fuel economy" = "miles per gallon" = (distance traveled) divided by (gallons used)

mpg = (226 miles) / (10.5 gallons) = 21.52 miles per gallon (rounded)

It makes absolutely no difference whether the trip took 4 hours or 4 years.
That information is there just to try and trip you up.  You don't need it.
