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

### Instruction:
Janet starts driving across a lake in a speedboat going 30 miles per hour. Her sister follows in a sailboat that has a speed of 12 miles per hour. If the lake is 60 miles wide, how long does Janet have to wait on the other side for her sister to catch up?

### Response:
 Kwanza tafuta muda ambao Janet anachukua kuvuka ziwa: 60 maili / 30 maili kwa saa = <<60/30=2>>2 masaa
Kisha tafuta muda ambao dada yake anachukua kuvuka ziwa: 60 maili / 12 maili kwa saa = <<60/12=5>>5 masaa
Kisha toa muda wa kusafiri wa Janet kutoka kwa muda wa kusafiri wa dada yake ili kupata tofauti: 5 masaa - 2 masaa = <<5-2=3>>3 masaa
