To use the tree house as the start of the zip line, the cable needs to be attached to the starting tree at a height of 16 feet above the graund. To meet the slope constraints, Vince wants to change the height 7 feet's and end the zip line at a height of 9 feet above the ground. He claims the vertical change meets the slope constraint. Test Vince's claim for tree A and tree B. Use specific numbers from the situations to justify nor refute whether having a vertical change of 7 feet will satisfy the slope constraint for each tree.

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
