A machine operator walks $2$ steps to a punch press and pushes a

button to activate the press. The press completes its stroke in $2\mathrm{.}5$

seconds. The operator then picks up the heavy part from the

machine and places it with adjustments into a box $($within reach$).$

She then slides the box $14$ inches onto a conveyor. Then she walks

$5$ steps and bends to pick up an empty box from the floor and

returns to the press and lays it aside $(5$ steps$).$
