Consider a four$-$step serial process with processing times given in the following list. There is one machine at e

and this is a machine$-$paced process.

Step $1$: $24$ minutes per unit

Step $2$:$19$ minutes per unit

Step $3$:$35$ minutes per unit

Step $4$:$15$ minutes per unit.

Assuming that the process starts out empty, how long will it take $($in hours$)$ to complete a batch of $88$ units?

Note: Do not round intermediate calculations. Round your answer to nearest hour.

$($x$)$ Answer is complete but not entirely correct.F$24$
