You didn't state the starting unit, but I assume you want pounds into kg. 
1lb = 0.45359237kg.
1.440 x 10^8lbs * 0.45359237kg/1lb = 65317301.28 or 6.531730128 x 10^7

Answer:

65317248 kg

Explanation:

In the United States mass is expressed in pounds (lb), which is an imperial unit of mass.

\(1\ lb=0.453592\ kg\)

\(\\\Rightarrow 1.44\times 10^8\ lb =1.44\times 10^8\times 0.453592\\\Rightarrow 1.44\times 10^8\ lb =65317248\ kg\)

The average mass of an automobile in the United States is 65317248 kg.
