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

### Instruction:
Jenny leaves her house at 8:00 with some cupcakes for her daughter's birthday party at school. She jogs to the school at 15 miles per hour. Half an hour later, her wife Anna realizes that Jenny used peanut butter frosting because she forgot one of the kids in the class had a severe peanut allergy. Jenny doesn't have her cell phone, so Anna leaves the house driving at 45 miles her hour to catch Jenny and warn her. How long does Anna spend traveling in minutes?

### Response:
 Tunajua kuwa muda ambao Anna anatumia kusafiri ni dakika 20 chini ya muda wa kusafiri wa Jenny: a = j - 20
Pia tunajua kuwa umbali ambao kila mtu anasafiri ni sawa, kwa hivyo kasi zao mara muda wa kusafiri lazima ziwe sawa: 15j = 45a
Kwa kubadilisha equation ya kwanza katika equation ya pili, tunapata 15j = 45(j - 20)
Kwa kutoa 20 kutoka pande zote mbili, tunapata 15 j = 45 j - 900
Kwa kuongeza 900 kwa pande zote mbili, tunapata 15 j = 45 j
Kwa kugawanya pande zote mbili na 15, tunapata j = 3 j
Kwa kugawanya pande zote mbili na 3, tunapata j = 30 dakika
Hivyo, Anna anasafiri kwa dakika 30 - 20 = <<30-20=10>>10 dakika
