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

### Instruction:
Keegan is in school for 7.5 hours each day and he is taking 7 classes. He has history and chemistry classes for a combined total of 1.5 hours. How many minutes does Keegan spend in one of his other classes on average?

### Response:
 Masaa 7.5 - masaa 1.5 = <<7.5-1.5=6>>6 masaa
6 masaa = <<6*60=360>>360 dakika
Keegan anatumia dakika 360 katika masomo 7 - 2 = <<7-2=5>>5 yake
Keegan anatumia dakika 360/5 = <<360/5=72>>72 katika mojawapo ya masomo yake mengine.
