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

### Instruction:
Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?

### Response:
 Ikiwa wanaweza kusafiri maili 100 kwa saa 1, basi maili zilizobaki 300 zitachukua masaa 300/100 = 3.
Jumla ya masaa waliyosafiri itakuwa 3 + 1 = <<3+1=4>>4 masaa.
