At 12:00 pm., Lou leaves her house and drives north to her parent's home. She arrives at 4:00 p. m. Also leaving at 1:00 Lou's house is her friend Amy who leaves and drives south to her parent's home. She arrives at 3:00 p. m. The driving distance between both parents' homes is 330 mi. Lou and Amy drove at the same speed. What was their speed? 60 m/h 55 mi/hi 45 m/h O 50 m/h

55 mph

Step-by-step explanation:

12pm-4pm is 4 hours

1pm-3pm is 2 hours

4+2 hours is 6 hours.

330 miles/6 hours is 55 mph

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.
