Charlie is helping his family design a sun porch for their house. It will be in the shape of a trapezoid (ABCD), allowing for large windows on several sides. Charlie has labeled the four corners A, B, C, and D. He wants to find out how many 12-inch-square floor tiles he should order if 2 dozen extra tiles are needed for replacements or cutting errors. The tiles come in boxes of 12 tiles per box.

Following is information about the dimensions of the sun porch.

Line BC is 20 feet long and runs along the living room.

Line AB is 8 feet long and is perpendicular to line BC.

Line CD is parallel to line AB but is twice as long as line AB.

Line AD represents the longest wall with the most windows.

Line AE is an imaginary line parallel to line BC.

Point E is on line CD. It is the midpoint of line CD.

How many boxes of floor tiles should Charlie order?

### Long Walk for Henry

Henry lives in a city laid out on a grid. Laid out on a map the vertical streets are A through Q. The horizontal streets are First through 17th.

Henry began his afternoon walk at 2:45, leaving from his house to visit a friend. For every 5 minutes he walked, he traveled north 2 blocks and east 1 block. He started on the corner of C Street and Second Avenue. He arrived at his friend's house at 3:10 in the afternoon.

Henry then spent 2 hours and 20 minutes at his friend's house. When he left, he walked to the store at the corner of K and Sixth Streets at the same rate as his earlier walk (though in a different direction). He spent 10 minutes at the store before walking home.

If he walked home at the same rate as his other walks, at what time did get home?
