The buffer of a computer system works according to the FIFO system (first in, first out). For simplicity, we assume that the actual occupancy of the buffer varies in a continuous manner over time. At a given time to, the occupancy of the buffer is identical to that of 3 milliseconds before. Show that there is at least one moment t, within that 3 millisecond time span for which the buffer occupancy was the same as 1 millisecond before t₁.

14. The buffer of a computer system works according to the FIFO system (first in, first out).
For simplicity, we assume that the actual occupancy of the buffer varies in a continuous
manner over time. At a given time to, the occupancy of the buffer is identical to that of 3
milliseconds before. Show that there is at least one moment t₁ within that 3 millisecond
time span for which the buffer occupancy was the same as 1 millisecond before t₁.
