Final answer:
The number of students on each car for both schools is approximately 3.
Step-by-step explanation:
To find out how many students were on each car, we need to divide the total number of students by the total number of cars.
For Taravella High School:
Total number of students = 56
Total number of cars = 12 minivans + 5 cars = 17
Number of students per car = 56 / 17 ≈ 3.294
For Coral Springs High School:
Total number of students = 45
Total number of cars = 7 minivans + 6 cars = 13
Number of students per car = 45 / 13 ≈ 3.462
Therefore, there were approximately 3 students on each car for both schools.
