Question

A train travelling at 120km/hr goes through a tunnel 155m long. Calculate in seconds,the time a passenger on the train spends in the tunnel​

Answer 1

Answer:

$120km. {hr}^{ - 1} \times \frac{5}{18} = 33.33m. {sec}^{ - 1} \\ d = vt \\ t = \frac{d}{v} = \frac{155m}{33.33m. {sec}^{ - 1} } \\ \boxed{t = 4.65sec}$
