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

### Instruction:
The school nurse must conduct lice checks at the elementary school. She must check 26 Kindergarteners, 19 first graders, 20 second graders, and 25 third graders. If each check takes 2 minutes, how many hours will it take the nurse to complete all the checks?

### Response:
The total number of students to be checked is 26+19+20+25 = <<26+19+20+25=90>>90 students
The total time for the nurse to complete all the checks is 90*2 = <<90*2=180>>180 minutes
180 minutes = <<180/60=3>>3 hours
The nurse will take 3 hours to complete all the checks.
