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

### Instruction:
 Joseph anataka kwenda Boston kwa safari ya barabarani. Ikiwa atachukua njia A, itamchukua masaa 5 kufika; lakini ikiwa atachukua njia B, itamchukua masaa 2 tu kufika kwenye marudio yake. Ataweza kuokoa muda kiasi gani ikiwa atachukua njia B kwenda Boston na kurudi nyumbani?


### Response:
 Muda unaookolewa kwa kwenda Boston ni masaa 5 - masaa 2 = <<5-2=3>>3 masaa
Muda unaookolewa kwa kurudi nyumbani pia ni masaa 3
3+3 = <<3+3=6>>6 masaa
