A train with a length of 150m long, takes 30 seconds to cross a 500m long bridge. How much time will the train take to cross a 370m long platform?
Solution
Correct Answer: Option B
Length of the train = 150 m
Length of the bridge = 500 m
Total length = (500 + 150)m
= 650m
Speed of the train = 650/30 m/sec
= 65/3 m/sec
Now,
total length of the train and new bridge = (370 + 150)m = 520m
∴ Time taken = (520 × 3)/65 sec
= 24 sec
Length of the bridge = 500 m
Total length = (500 + 150)m
= 650m
Speed of the train = 650/30 m/sec
= 65/3 m/sec
Now,
total length of the train and new bridge = (370 + 150)m = 520m
∴ Time taken = (520 × 3)/65 sec
= 24 sec
