Question

the length of the bridge which the train 130 meters long and travelling at 45km/hr can cross in 30 sec is​

Answer 1

Answer:

⭐ SOLUTION ⭐

✏ The length of bridge = xm

✏ The length of train = 130m

✏ Speed = 45km/hr

= 45×5/18

= 25/2

Distance | 25/2 | 130+x

Time | 1 | 30

✏ It vary directly

Therefore,

=> 25/2 = 130+x/30

=> 130+x = 25/2 × 30

= 375

=> 130+x = 375

=> x = 375-130

=> x = 245 ( Ans)
