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>
