Diane and douglas both drive at an average rate of 50 miles per hour. diane travels 20 miles further than douglas. diane drives for at least 2 hours, but no more than 4 hours. which statement correctly describes the range of distances that douglas may drive? a.) douglas drives at least 80 miles, but no more than 180 miles. b.) douglas drives more than 80 miles, but less than 180 miles. c.) douglas drives more than 120 miles, but less than 220 miles. d.) douglas drives at least 120 miles, but no more ham 220 miles

so if diane drives for 2 hours, she travels about 100 miles. if she drives for 4 hours, she drives about 200 miles. if we subtract 20 from each of these, we get 80 and 180. the answer is A.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
