- A 300 meter long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds.
Question 1:
A 300 meter long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform? A. 150 m
B. 200 m
C. 350 m
Feedback Speed = [300 / 18] m/sec = 50/3 m/sec.
Let the length of the platform be x meters.
Then, x + 300 / 39 = 50/3
3(x + 300) = 1950 x = 350m.
Let the length of the platform be x meters.
Then, x + 300 / 39 = 50/3
3(x + 300) = 1950 x = 350m.
D. 400 m
