Question

Have vehicles gotten more fuel-efficient over the years? Between 1960 and 1999 the size and shape of automobiles in the United States has changed almost annually. The amount of fuel consumed by these vehicles has also changed. The following table describes the average fuel consumption per year per passenger car in gallons of gasoline.

Year, t 1960 1970 1980 1990 1995 1997 1998 1999
Gallons Consumed Per Passenger Car

no clue

Answer 13

I'd say:
$$
\frac{\Delta g}{\Delta t} = \frac{760 - 668}{1970 - 1960} = \frac{92}{10} = 9.2
$$
