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

### Instruction:
 Andy anatembea mita 50 kutoka nyumbani kwake kwenda shule. Baada ya shule, anarudi nyumbani na kwenda sokoni. Ikiwa anatembea jumla ya mita 140, umbali kati ya nyumba na soko ni mita ngapi?


### Response:
 Andy kwanza anatembea mita 50 kutoka nyumbani kwenda shule na kisha anatembea tena mita 50 kutoka shule kwenda nyumbani, hivyo anatembea mita 50 + 50 = <<50+50=100>>100
Ikiwa Andy anatembea mita 140 jumla, umbali kati ya nyumba na soko ni mita 140 - 100 = <<40=40>>40.
