Answer:

40 teachers.

Step-by-step explanation:

  • The required staff to student ratio is 2:15
  • 340 people attended the excursion.

We are to find the number of teachers (staff) who attended the excursion).

For every 2 staff, there are 15 students

The number of teachers who attended the excursion is [tex]\frac{2}{17}[/tex]  × 340 = 40 teachers

The number of students who attended the excursion is [tex]\frac{15}{17}[/tex] × 340 = 300
