How to add two equal sized lists into one list with key pairs

In Android Studio, I have two lists, specifically:

val distanceResults = Pair(mutableListOf<String>(), floatArrayOf())

It's a pair where each item is its own list; these sublists will always be the same length.

What I need to do is take each index of each list and merge them into one list. So that the end result would look something like:

    list1 -> ("A", "B", "C")
    list2 -> (1F, 2F, 3F)
    finalList -> (
        ["A", 1F],
        ["B", 2F],
        ["C", 3F],
    )

I'm not sure if a filter, flatFiler, map, or something else would do the trick.
