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

### Instruction:
The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book. If he has a 4000-page book, how many pages does he read in an hour if he takes 4 hours to move from his office to grab lunch?

### Response:
 Ikiwa Juan anachukua masaa 4 kusafiri kutoka ofisini kwake kuchukua chakula cha mchana, kusafiri kutoka ofisini kwake na kurudi kunachukua masaa 2*4=8.
Muda ambao Juan anachukua kuchukua chakula chake cha mchana kutoka ofisini kwake na kurudi ni nusu ya muda anachochukua kusoma kitabu, maana yake anasoma kitabu kwa masaa 2*8=<<2*8=16>>16.
Ikiwa ana kitabu cha kurasa 4000, atakisoma 4000/16=<<4000/16=250>>250 kurasa kwa saa.
