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

and this $is$ a machine$-$paced process.

Step $1$: $16$ minutes per unit

Step $2$: $15$ minutes per unit

Step $3$: $22$ minutes per unit

Step $4$: $12$ minutes per unit

Assuming that the process starts out empty, how long will $it$ take $(in$ hours$)to$ complete a batch $of98$ units?

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