Question

48. A train of certain length traveling with a uniform
speed of 36 km h- crosses a bridge of 600 m in 80 s.
Find the length of the train.​ i need answer now pls​

Answer 1

$\large\underline{\underline{\sf Given:}}$

Speed of train (S) = 36km/h

Convert it into m/s

$\large\implies{\sf S=36×\frac{5}{18}}$

$\large\implies{\sf S=10m/s }$

Bridge Lenght = 600m

Time (t) = 80s

$\large\underline{\underline{\sf To\:Find:}}$

Lenght of train (L) = ?

$\large\underline{\underline{\sf Solution:}}$

${\boxed{\sf Speed=\frac{Total\: Distance}{Total\:Time}}}$

$\large\implies{\sf 10=\frac{600+L}{80}}$

$\large\implies{\sf 10×80=600+L}$

$\large\implies{\sf L=800-600}$

$\large\implies{\sf L=200m}$

$\Large\underline{\underline{\sf Answer:}}$

•°• Lenght of train is 200m
