The distances of two trains from a station can be represented by the equations shown, with t being the time in hours and d being the distance in miles. Train A's distance from the station is given by d = 80t + 450
Train B's distance from the station is given by d = 60t + 850

How many hours after the trains left the station will the two trains be the same distance from the station, and what will the distance be?

A. 20 hours, 400 miles
B. 140 hours, 2050 miles
С. 20 hours, 2050 miles
D. 10 hours, 400 miles​

As a project for math class, two students devised a game in which 3 black marbles and 2 red marbles are put into a bag. first the players must decide who is playing black marbles and who is playing red marbles. then each player takes a turn at drawing a marble, noting the color, replacing the marble in the bag, and then drawing a second marble and noting the color before returning it to the bag. the point scheme for the game is detailed in the table below. point values for marble game black marble points red marble points both black: +2 points both red: +4 points different colors: –1 point different colors: –1 point both red: 0 points both black: 0 points
