If a train that's heading west leaves a station at the same time that an eastbound train 840 miles away leaves it's station. they both travel at an average speed of 120 mph how long will it take before they meet?


Rate This Answer

Train Station Here's the deal: The trains are 840 miles apart and each is traveling 120 mph towards each other. That means they have a combined speed of 240 mph. 840/240 = the trains pass each other in 3.5 hours.
