873 pedestrians/ minute = pedestrians/ hour

At the same rate, ...

... 873 ped / min = (60 × 873 ped) / (60 × 1 min) = 52,380 ped / hour

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.
