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

### Instruction:
James can do a farmer's walk with 300 pounds per hand for 20 meters.  He can lift 30% more if he only goes 10 meters.  In addition, lifting straps give him another 20%.  How much can he move with lifting straps for 10 meters if he increases his 20-meter distance without straps by 50 pounds and everything else increases in proportion?

### Response:
 Kuongeza uzito kwa kilo 50 kwa mita 20 kunamaanisha uzito ni 300+50=<<300+50=350>>350 kwa kila mkono
Kupunguza umbali kunazidisha uzito anaweza kubeba kwa kilo 350*.3=105 kwa kila mkono
Hivyo anaweza kubeba kilo 350+105=<<350+105=455>>455 kwa kila mkono kwa mita 10
Vifungo vinaongeza kilo nyingine 455*.2=91
Hivyo uzito wake jumla ni 455+91=<<455+91=546>>546 kwa kila mkono
