Two Trains A and B start simultaneously from stations 500 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 50 miles per hour and 50 miles per hour, respectively, how many miles will Train A have traveled when the trains pass each other, to the nearest mile? Choices: A) 112 B) 133 C) 150 D) 250 E) 288
Since we know the distance (500) and the combined rate (100), we plug it into the formula:   Distance = Rate * Time   500 = 100 * 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 500/100 from dividing 100 on both sides to isolate Time in the equation above.   Time will be 5 hours so now you can plug that in for Train A’s distance.   250istance = Rate * Time   250istance = 50 * 5   250istance = 250 according to answer choice 250.
