Solid waste from an industrial park is to be collected in large containers, some of which will

be used in conjunction with stationary compactors. Based on traffic studies at similar parks,

it is estimated that the average time to drive from the garage to the first container $($t$1)$ and

from the last container $($t$2)$ to the garage each day will be $15$ and $30$ minutes, respectively. If

the average time required to drive between containers is $6$ minutes and the one$-$way

distance to the disposal site is $30km($speed limit: $88k\frac{m}{h})$;

i$)$ Determine the number of containers that can be emptied per day, based on a $7-$hour

working day.

ii$)$ The collectors claimed that they spend less than $15$ percent of each $7-$h workday on off$-$

route activities. From this information, decide whether the truth is on the side of the

collectors or the management. Is that possible for the management to increase $1$ more

collection trip?

Given:

Pick up time per trip: Phcs $=pc+uc+dbc$

Time per trip, Thcs $=(Phcs+s+a+bx)$

Number of trips that can be made per day; $Nd=\frac{H(1-W)-(t1+t_2)}{?}$ Thcs
