Detailed Solution
Download Solution PDFGiven:
Length of Train 1 = 195 m
Length of Train 2 = 181 m
Speed of Train 1 = 19 m/s
Speed of Train 2 = 28 m/s
Formula Used:
Relative Speed = Speed of Train 1 + Speed of Train 2 (since they are moving towards each other)
Time = Total Distance / Relative Speed
Calculations
Total Distance = Length of Train 1 + Length of Train 2
Total Distance = 195 m + 181 m = 376 m
Relative Speed = 19 m/s + 28 m/s = 47 m/s
Time = Total Distance / Relative Speed
Time = 376 m / 47 m/s
Time = 8 seconds
∴ The trains will take 8 seconds to cross each other
