Whitney drew a scale drawing of a restaurant. She used the scale 2 millimeters : 7 meters. If the restaurant's kitchen is 8 millimeters long in the drawing, how long is the actual kitchen?
meters
To find the actual length of the kitchen, we can use the given scale. Since the scale is 2 millimeters : 7 meters, 1 millimeter in the drawing represents 7/2 = 3.5 meters in reality.
Since the kitchen is drawn as 8 millimeters, the actual length of the kitchen is 8 * 3.5 = <<8*3.5=28>>28 meters. Answer: \boxed{28}.
