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​
