Dr$.$ Gretta Raider's process at her PCP practice is as follows:

What is the bottleneck time throughput time of this process?

Bottleneck is $60$ units$/$hour and Throughput is $6mi\frac{n}{u}$nit

Bottleneck is $60$ units$/$hour and Throughput is $110$ units$/$hour

Bottleneck is $2mi\frac{n}{?}$ unit and Throughput is $110$ units$/$hour

Bottleneck is $2mi\frac{n}{?}$ unit and Throughput is $6mi\frac{n}{?}$ unit

Bottleneck is $2mi\frac{n}{u}$nit and Throughput is $4\mathrm{.}5mi\frac{n}{u}$nit

Bottleneck is $60$ units$/$hour and Throughput is $4\mathrm{.}5$ units$/$hour
