The average fleet-wide performance of light duty trucks has made constant improvement since 1980. for example, the time for the average 1080 light-duty truck to accelerate from 0 to 60 mph was about 14.5 seconds. for 2005 models, that time was only 10.5 seconds. a) let m be the model year of a light-duty truck and t be the time in seconds for it to accelerate from 0 to 60 mph. write a linear function t(m) to model the situation. b) use your answer to part (a) to predict the time it will take the average light-duty truck to accelerate from 0 to 60 mph in 2015, if the trend continues.
