Olive Dorsey · Answer 1

Minimum 08 adults / drivers

Maximum 10 adults / drivers

Step-by-step explanation:

Total students are 30

Each car can take total 5 incl. drive

There needs to be 7 cars taking the 30 students, which also means there have to be minimum 7 drivers / adults.

Min. passengers = 30 + 7

Of course, there will be space for 3 more in the 8th car since 5 x 8 = 40

15 because you have to divide by 2
