Team Careers360 · Accepted Answer

Correct Answer: 7.2 sec

Solution : Length of train = 200 m
Speed of train = 100 km/hr
1 km/hr = $\frac{5}{18}$ m/sec
100 km/hr = $100 imes \frac{5}{18}=\frac{250}{9}$ m/sec
Time = $\frac{ ext{Distance}}{ ext{Speed}}=\frac{200}{(\frac{250}{9})}=7.2$ sec
Hence, the correct answer is 7.2 sec.
