Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jackie loves to climb trees.  She climbed a 1000 foot tall tree.  Then she climbed 2 trees that were half as tall as the first tree.  She finished by climbing a tree that was 200 feet taller than her first tree.  What was the average height of the trees that Jackie climbed?

### Response:
 Jackie alipanda miti 2 ambayo ilikuwa 1/2 * futi 1000 = futi 500 kila moja.
Jackie alipanda mti wa mwisho ambao ulikuwa mrefu kwa futi 1000 + 200 = <<1000+200=1200>>1200.
Jumla ya miti 4 ambayo Jackie alipanda ilikuwa futi 1000 + futi 500 + futi 500 + futi 1200 = <<1000+500+500+1200=3200>>3200.
Urefu wastani wa miti ambayo Jackie alipanda ulikuwa futi 3200 / miti 4 = <<3200/4=800>>800.
