Could anyone help me with this question.
Andrew drove his truck 100 miles, rounded to the nearest 10 miles, and used 10 gallons of gasoline, rounded to the nearest gallon. The actual number of miles per gallon that Tom’s truck got on this vacation trip must have been between
d = 100 miles (rounded to nearest miles) so it will be
g = 10 g
miles / gallon = d/g
To maximize this we need to maximize d and minimize g = 110/9= 12.22
To minimize this we need to minimize d and maximize g = 100/11 = 9.11
9.11 < mpg < 12.22
