Answer:
3 buses and 5 cars
Explanation:
There were a total number of 8 vehicles used to carry the students and 110 students in total.
The maximum number of buses there could have been was 3 because 30 goes into 110 3 times so there is 3 buses.
This leaves 20 students remaining and each car could carry 4 students.
20 divided by 4 = 5 which meant there were 5 cars.
This means there must have been 5 cars and 3 buses taken to the beach.
