Q:-How long will a train,120m long, take to clear a plateform , 130m long , if it's speed is 50km/ hr ?

$\huge\tt\underline\blue{ANSWER }$

------>>>>Here is your answer<<<<--------

⇒Length of train =120m

⇒length of platform=130m

⇒Total length =120+130=250m

speed of train is given in km/hr=50km/hr

so we have to convert into m/s:-

$⇒50 \times \frac{5}{18} = \frac{250}{18} m/s$

$⇒time = \frac{distance}{speed}$

The required time:-

$⇒ \frac{250}{ \frac{250}{18} } = 250 \times \frac{18}{250} =18m /s</p><p>$

∴The time required by the train is 18m/s

HOPE IT HELPS YOU..
