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

### Instruction:
Sonia and Joss are moving to their new house at the lake. They have too much stuff in their previous house and decide to make multiple trips to move it all to the new house. They spend 15 minutes filling the car with their stuff and spend 30 minutes driving from the previous house to the new house. Fortunately, they did not waste any time unloading their stuff into the new house. In total they make 6 trips to complete the move. How many hours did they spend moving?

### Response:
 Walitumia dakika 15/safari + dakika 30/safari = <<15+30=45>>45 dakika/safari.
Walilazimika kufanya safari kwenda nyumba mpya mara 6, hivyo walitumia 45 dakika/safari x 6 safari = <<45*6=270>>270 dakika kusafiri.
Pia walilazimika kurudi nyumbani kwao mara 5 ili kukamilisha uhamisho: 30 dakika/safari x 5 safari = <<30*5=150>>150 dakika.
Jumla yake, walitumia dakika 270 + dakika 150 = <<270+150=420>>420 dakika kusafiri.
Kila saa ina dakika 60 hivyo walitumia dakika 420 ÷ dakika 60/saa = <<420/60=7>>7 masaa jumla.
