An automated assembly line adjusts conveyor speed S(p) in meters per second based on hydraulic pressure p in kilopascals according to a linear function. When pressure p = 15, speed S = 4.0, and when pressure p = 35, speed S = 9.0. If pressure p is constrained such that 2.0 ≤ S(p) ≤ 11.5
What is the range of permissible values for pressure p?
- 7 ≤ p ≤ 45
- 8 ≤ p ≤ 46
- 9 ≤ p ≤ 47
- 5 ≤ p ≤ 43
- 0.25 ≤ p ≤ 2.375
