• A. 4 seconds
• B. 12 seconds
• C. 30 seconds
• D. 15 seconds

Answer 1

Answer:

B. 12 seconds

Solution:

Given:

Length of Train = 180 m

Speed of Train = 54 km/hr $= 54\times{\frac{5}{18}}m/sec$

$=3\times{5}=15 m/sec$

Time taken by the train to cross the man standing on the platform $=\frac{180}{15}=12 sec$
