#=>11# trips

Explanation:

We have #32# total miners. The elevator takes #3# miners at a time.

If we divide our total by the number of miners per trip, that will give us the number of trips:

#32 / 3 = 10 " r " 2#

So the elevator will make #10# trips, but then there will still be #2# miners remaining. So even though the elevator will not be full, we need #1# additional trip to take the remaining #2# miners.

So the total number of trips needed is #11#.
