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

### Instruction:
Christina and her friend are driving across the state. When Christina is driving the speed limit is 30 miles per hour. When her friend is driving, the speed limit is 40 miles per hour. The drive is 210 miles total. If her friend drives for 3 hours and both drive at the speed limit, how many minutes will Christina drive?

### Response:
 Rafiki anaendesha 40*3=<<40*3=120>>120 maili
Wote wanaendesha 120+90=<<120+90=210>>210 maili
Christina anaendesha 210-120=<<210-120=90>>90 maili
Kwa kuwa kikomo cha kasi ni maili 30 kwa saa wakati Christina anaendesha, anaendesha kwa masaa 90/30=<<90/30=3>>3, au dakika 180.
