Question

32 miners need to ride the elevator to the bottom of the mine. The elevator can hold 3 miners at a time. How many trips will the elevator need to make?

Answer 1

`=>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`.
