1. A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?
- A. 80. Sec
- B. 80. Sec
- C. 80. Sec
- D. 80. Sec
Answer: Option B
Explanation:
Given:
Length of the train = 240 m
Time taken to cross the pole = 24 s
Length of the platform = 650 m
Concept Used:
Time take into the platform = (length of train + length of the platform)/speed of the train
Speed of train = length of train/time taken
Calculation:
Speed of train = 240/24 = 10 m/s
Time taken to cross the platform = (240 + 650)/10 = 890/10= 89 s.
