A train leaves Station A at 60 mph. Two hours later, a faster train leaves Station A on the same track at 90 mph. How many hours after the first train departs does the second train catch up?

How Long Does It Take for a Faster Train to Catch a Slower One? A Step-by-Step Breakdown When two trains travel the same route on identical tracks, the pursuit becomes a classic example of relative motion. In this scenario, a train departs Station A at 60 miles per hour (mph), and two hours later, a faster train leaves the same station traveling at 90 mph. The question is: how long after the first train’s departure does the second train catch up? Let’s break it down using basic physics and distance-time relationships. ---
