Question $2$

Considering that the arm is initially positioned at Track $11,$ moving toward the low$-$numbered tracks, and using the LOOK scheduling policy, let's compute the total seek time to satisfy the following requests$-4,40,35,11,14,$ and $7,$ assuming all requests are initially present in the wait queue. $($Rotational time and transfer time are ignored; only seek time is considered.$)$

Seek time is $4m\frac{s}{?}$ track, search time is $1\mathrm{.}7m\frac{s}{?}$ sector, and data transfer time is $0\mathrm{.}6ms.$
