The answer is the last one.
Corresponding sides are proportional.
For figures to be considered similar, the ratio of their sides must be proportional.
You need to figure out the rates at which they both work.
<span>For Jenny, its 250 pieces / 3 hours = 83.3 pieces / hour </span>
<span>For her brother, its 250 pieces / 6 hours = 41.7 pieces / hour </span>
<span>so together, that adds up to 125 pieces / hour. </span>
<span>(125 pieces / hour) = (1/125) hours / piece </span>
<span>(1/125) hours / piece * 250 pieces = 2 hours because the pieces on the top and bottom cancel </span>
<span>so the answer is 2 hours</span>
