But to run faster over 26.2 miles, you have to increase your endurance. If youâre a 41 year old woman and you can run a 4:00 marathon (or about 9 minutes per mile), an ambitious goal would be to qualify for Boston in 3:45 (5 minutes under the BQ time).y the end of my Philadelphia training, my long run was 22 miles with 3 x 3 miles during the second half in 18:48, 18:05, and 17:46 with a mile recovery in between each. I ran 15 miles with 8k at progressively faster than marathon pace.
In a translation, every point of the object must be moved in the same direction and for the same distance. When you are performing a translation, the initial object is called the pre-image, and the object after the translation is called the image. So, in the picture above, the rust-colored item is the pre-image, and the blue item is the image.
In the example below, notice how each vertex moves the same distance in the same direction. In this next example, the slide (translation) moves the figure 7 units to the left and 3 units down. There are several ways to indicate that a translation is to occur:1. description: 7 units to the left and 3 units down. (A verbal description of the translation is given.) 2. mapping: (This is read: the x and y coordinates will be translated into x-7 and y-3.Notice that adding a negative value (subtraction), moves the image left and/or down, while adding a positive value moves the image right and/or up.). 3.The -7 tells you to subtract 7 from all of your x-coordinates, while the -3 tells you to subtract 3 from all of your y-coordinates.) This may also be seen as T-7,-3(x,y) = (x -7,y - 3). 4. vectors: (A vector, a directed line segment, may also be used to show the movement of a translation.
