1. A friend claims that a metric ton is more than twice the mass of an English ton because a kilogram is more than twice the mass of a pound. Make a quantitative argument in support of or against your friend's claim. (1 page) 2. Upgraded U.S. fuel economy standards formalized in 2012 call for a 54.5 mile-per-galloon average for new cars and light trucks in 2025. A politician opposing this increase claims it will save "only a drop in the bucket" compared with the 2014 fleet average of about 23 mpg. Formulate a counterargument showing that the increase - once the entire fleet reaches 54.5 mpg - consumption rate from its 2014 value of about 375 million gallons per day. State any additional assumptions you make.
