Does the data in the table represent a direct variation or inverse variation? write an equation to model the data in the table. (making my own table) (x) 2 l 4 l 8 l 12 l (y) 10 l 5 l 5/2 l 5/3 a: direct variation; y=20x b: inverse variation; xy= 20 c: inverse variation; y/x= 20 d: direct variation; y= 20/x

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling
