A train 200 m long can cross an electric pole in 20 sec and then find the speed of the train?
Answer/Solution
36 Kmph
Steps/Work
Length = Speed * time
Speed = L/T
S = 200/20
S = 10 M/Sec
Speed= 10*18/5 (To convert M/Sec in to Kmph multiply by 18/5)
Speed = 36 Kmph
Answer: D
Speed = L/T
S = 200/20
S = 10 M/Sec
Speed= 10*18/5 (To convert M/Sec in to Kmph multiply by 18/5)
Speed = 36 Kmph
Answer: D
