Answer 2

Ans:

The train will take 12.26 seconds to cross the pole

Step-by-step explanation:

First, we will convert given speed in m/s, which is given in km/h  

Hence we will multiply given speed to $\dfrac{5}{18}$ to convert it into m/s

=$60\times\dfrac{5}{18}$=16.3m/s

Now as we know that $T=\dfrac{D}{S}$

Therefore $T=\dfrac{200}{16.3}=12.26s$
