10-72.

Each morning, Jerry delivers the Times to one neighborhood and then the Star to a different neighborhood. While delivering the Times, Jerry delivers $2$ papers per minute. However, since the Star is so heavy, he can only deliver $1$ Star paper per minute. If he delivers a total of $91$ papers and takes exactly an hour to deliver all papers, how many of each type of paper does he deliver?

Let x represent the number of Times delivered, and y represent the number of Star papers delivered.
Set up a system of equations.

$\left\{\begin{matrix} .5x+y=60\\ x+y=91 \end{matrix}\right.$
