Easy
A pulse-tracer C-curve rises linearly from 0 at t=0 to 1 at t=1s, then falls linearly back to 0 at t=2s (zero afterward). The mean residence time, rounded to 1 decimal place, is
1 s(± 0.05 accepted)
Explanation
The triangular C(t) curve is symmetric about t=1s, so the mean residence time (first moment) equals 1.0s by symmetry.
