Question

150 meters long train crosses a platform of length 250 meters in 30 secs. Find the time for train to cross a bridge of 130 meters?y​

Answer 1

Answer:

15.6 secs

Step-by-step explanation:

Dude its very easy...just follow my steps....

Just forget the size of train

Applying unitary method,

250 meters crossed in 30 secs

Hence,

1 meter crossed in $\frac{30}{250}$ secs

Thus,

130 meters crossed in $\frac{30}{250}* 130$ secs

                                   = $\frac{390}{25}$ = $15.6$ secs

Hope it helps you buddy....
