1. When solving for the arrival rate λ, it should be λ=ρ/S instead of λ=S/ρ.
2. Calculating the arrival rate λ with the correct formula results in 9 requests/second instead of 10 request/second.
3. Calculating the new utilization ρ should be 0.05x9 instead of 0.05x10.
The result of the calculated utilization ρ is correct (0.45), so is the calculated new latency.

λ = S/ρ = 0.1/(1−0.9) = 10
Should be 1 not 10.
