Answer: It will take 1.8 hours for the two trains to meet.
Step-by-step explanation:
Since we have given that
Speed of one train = 75 mph
Speed of other train = 95 mph
Since they travel towards each other.
so, Relative speed = 75+95 = 170 mph
Distance between them = 306 miles
We need to find the time taken:
So, it becomes,
Hence, it will take 1.8 hours for the two trains to meet.
