Answer:

hey mate

Step-by-step explanation:

let the no of rungs in ladder is x

kathy stood in middle so it mean kathy stood on x/2 rungs

She climbed up 3 rungs, moved down 4 rungs, and then climbed up 6 rungs. Then she climbed up the remaining 4 rungs to the top of the ladder.

x/2 +3-4+6 = -4+x

x/2-x = -9

x = 18 rungs
