From Mumbai railway station,two Trains A and B start simultaneously from stations 400 miles apart, and travel the same route toward each other on adjacent parallel tracks. If Train A and Train B travel at a constant rate of 40 miles per hour and 40 miles per hour, respectively, how many miles will Train A have traveled when the trains pass each other, to the nearest mile?	Pick.
A) 112
B) 133
C) 150
D) 167
E) 180
Since we know the distance (400) and the combined rate (80), we plug it into the formula:   Distance = Rate * Time   400 = 80 * Time   We can solve for the time they will meet cause we added the rate of Train A and Train B together.   So the time will be 400/80 from dividing 80 on both sides to isolate Time in the equation above.   Time will be 20 hours so now you can plug that in for Train A’s distance.   Distance = Rate * Time   Distance = 40 * 20   Distance = 180 according to answer choice 180.
