While researching, Ichiro found that a gasoline car can drive 210,000 miles on average over
its lifetime (period of time a car can operate).
A plug-in hybrid car can drive a lifetime of
300.000 miles.
Consider two families that each drive 15.000
miles a year for the lifetime of the car one
with a gasoline car and the other with a plug-in
hybrid.
What is the percent decrease for the pounds
of CO2 that the plug-in hybrid car would emit
over its lifetime as opposed to the gasoline car?
Round your final percentage to the nearest
integer.
