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

### Instruction:
Rich likes to take long walks through town.  First he walks 20 feet from his house to the sidewalk.  Then he walks 200 feet down the sidewalk to the end of the road.  Then he makes a left and walks double his total distance so far until he reaches the next intersection.  Then he walks half the total distance up to this point again to the end of his route, before turning around and walking the same path all the way back home.  How many feet did Rich walk?

### Response:
 Rich anatembea futi 20+200= <<20+200=220>>220 kufika mwisho wa barabara.
Kisha anatembea mara mbili ya umbali huo, 220*2= <<220*2=440>>440 futi hadi kwenye kona inayofuata.
Hii inafanya jumla ya futi 220+440= <<220+440=660>>660.
Kisha anatembea nusu ya umbali huo, 660/2= <<660/2=330>>330 futi kufika mwisho wa njia yake.
Hii inafanya jumla ya futi 660+330= <<660+330=990>>990 hadi sasa.
Kisha anatembea umbali huo huo kurudi, kwa jumla ya futi 990*2= <<990*2=1980>>1980.
