Find the length between landmark A and E A map shows a grid 17 units across and 12 units high, superimposed over shapes that represent streets and buildings. A key lists buildings located in Washington D.C. that correspond to points on the grid. Point A represents the White House. It is located at 4 units across from the left, and 3 units down from the top. Point B represents the Washington Monument, located at 5 units across and 9 units down. Point C represents the Natural History Museum, and is located at approximately 8 units across and 8 units down. Point D represents the Smithsonian, and is located at 10 units across and 10 units down. Point E represents the National Portrait Gallery, and is located at 12 units across and 3 units down. Point F represents the National Gallery of Art, and is located at 14 units across and 8 units down. A scale shows 200 feet and 200 meters.
To find the length between landmark A (White House) and E (National Portrait Gallery), we first need to calculate the horizontal and vertical distances between the two points on the grid.
Horizontal distance:
12 units - 4 units = 8 units
Vertical distance:
3 units - 3 units = 0 units
Now, using the scale of the map (200 feet and 200 meters), we can convert the grid units to actual distance:
8 units * 200 feet = 1600 feet
Therefore, the length between landmark A (White House) and E (National Portrait Gallery) is 1600 feet.
