Two trains, 163 m and 117 m long, are moving in the same direction at speeds of 93 km/hr and 33 km/hr, respectively. How much time will the faster train take to completely cross the slower one?
Given
Length of faster train = 163 m
Length of slower train = 117 m
Speed of faster train = 93 km/h
Speed of slower train = 33 km/h
Formula Used
Distance = Speed × Time
Relative Speed (same direction) = Speed 1 - Speed 2
Solution
Relative speed = 93 - 33 = 60 km/h
Convert into m/s = m/s
Total distance to cross = 163 + 117 = 280 m
Time taken = Total Distance ÷ Relative Speed
Time =
Time =
Time = 16.8 seconds
Final Answer
So the correct answer is (d)
