Find the total distance to clear:
Total distance = 210 + 165 = 375 m = 0.375 km
Find the time needed to clear the platform:
Speed = 50 km/h
Distance = 0.375 km
Time = Distance ÷ Speed
Time = 0.375 ÷ 50
Time = 3/400 hour
Time = 3/400 x 60 = 9/20 mins
Time = 9/20 x 60 = 27 seconds
Answer: It takes 27 seconds to clear the platform
