A train, 140 m long, passes a signal pole in 10 seconds. Find the spee – InterviewSolution

1.	A train, 140 m long, passes a signal pole in 10 seconds. Find the speed of the train in m/s and km/h
Answer» The SPEED of TRAIN in m/s and km/h is 14 m/s & 3.9 km/h respectively.Step-by-step EXPLANATION:GIVEN that,Distance (D) = 140mTime (T) = 10sAs we KNOW that,✒ Speed (S) = Distance (D) / Time (T) [ Putting values ]➡ S = 140/10➡ S = 14m/sNow, m/s convert into km/h ; so,✒ S = 14 × 5/18 ➡ S = 0.78 × 5➡ S = 3.9km/hHence Solved!!
