A 120m long train with a constant speed of 10.0m/s is passing by a 80.0m long train traveling at 6.0m/s on the opposite lane. How long does it take for these two train to completely pass by each other if their distance in between is 260m?
The Attempt at a Solution
Total distance Train A has to cover: 260m+80m= 340m
Total distance Train B has to cover: 260m+120m= 380m
Train A's Time = 340m / 10m/s
Train B's Time = 380m / 6m/s
Then im not sure what to do next but i'm given the answer of 28.8s...
