A train leaves Chicago at 10:00 AM and travels at a speed of 60 miles per hour. Another train leaves St. Louis at 11:00 AM and travels towards Chicago at a speed of 70 miles per hour. If the distance between Chicago and St. Louis is 300 miles, at what time will the two trains meet?

A
2:00 PM
💡 Explanation:
The first train travels for 1 hour before the second train leaves. In that time, it travels 60 miles. So, when the second train leaves, there are 240 miles left to travel. The two trains are traveling at a combined speed of 130 miles per hour. So, it will take them 2 hours to travel the remaining distance. Therefore, they will meet at 2:00 PM.
