• # question_answer A 205m-long train travelling at the speed of 54 kmph can cross a platform in 22 seconds. If a man can cross the same platform in 2 minutes, then what is the speed of the man? (in m/s) A)  1.51                             B)  1.04                 C)         1.07                 D)         1.95 E)  1.05

Let the length of the platform be lm. So,$(l+205)=54\times \frac{5}{18}\times 22$ or,$l=330-205=125\,\,m$ Now. speed of the man$=\frac{125}{2\times 60}=\frac{25}{24}$ $=1.04\,\,m/s$
