To find out how many students were in each bus, we first need to calculate the total number of students who rode the buses.
Given that 472 students were on the trip and 4 students rode in cars, we can calculate the number of students who rode the buses:
Total students on buses = Total students - Students in cars Total students on buses = 472 - 4 = 468 students
Now, if 468 students filled 9 buses, we can find out how many students were on each bus by dividing the total number of students on the buses by the number of buses:
Students per bus = Total students on buses / Number of buses Students per bus = 468 / 9 = 52
Therefore, there were 52 students in each bus.
The correct response is 52 students.
