की गति क्या थी?​

Answer 1

Answer:

(1)

[{MathJax fullWidth='false'

s=\dfrac{d}{t}\\

s=\dfrac{110}{13.5}\\

s=8.14 m/s }]

(2)

[{MathJax fullWidth='false'

s=\dfrac{d}{t}\\

s=\dfrac{205}{18.25}\\

s=11.23 m/s }]

Explanation:

As the train cover 110 m long platform in 13.5 s then it covers 8.14 m/s

And when the train covers 205 m long platform in 18.25 s then it covers in 11.23 m/s
