Then, the average waiting time T (in mins) for each vehicle arriving at the park is given by the rational function defined by T(r)=2r-k/2r^2-2kr where r is greater than K.
a. K is equal to 25 use graphing to estimate rate r that is necessary to keep the average waiting T to 30 secs.
b. if the park attendant can serve 5.3 vehicles/min, how many park attendants will be needed to keep the average wait to 30 secs.
