The time taken by a train 180 m long, travelling at 42 kmph, in passing a person walking in the same direction at 6 kmph, will be
Answer & Solution
Correct Answer:
Option
A
Speed of train relative to man
= (42 - 6) kmph = 36 kmph
= $$\left( {36 \times \frac{5}{{18}}} \right)$$ m/sec
= 10 m/sec
∴ Time taken to pass the man
= $$\frac{{180}}{{10}}$$ sec
= 18 sec
= (42 - 6) kmph = 36 kmph
= $$\left( {36 \times \frac{5}{{18}}} \right)$$ m/sec
= 10 m/sec
∴ Time taken to pass the man
= $$\frac{{180}}{{10}}$$ sec
= 18 sec
