Question

a 600 metre long train crosses a signal of 40 seconds how long will it take to process 3 km long Bridge at the same speed​

Answer 1

Answer:

240 sec

Step-by-step explanation:

formula for time taken to cross a signal or a pole or a man is

length of the train/ speed of the train

600/x= 40

x=15

formula for time taken to cross a bridge is

(length of train + length of bridge)/speed of train

600+ 3000/15

3600/15

240 sec

Answer 2

Answer:

4 Min

Step-by-step explanation:

Formula: Distance = Speed * Time

Length of Train = 600 m

Time = 40 s

Speed = Length / Time

           = 600 / 40

           = 15 m/s

3 km = 3000 m

D = (3000 + 600) m = 3600 m

Time = (3600 / 15) s

        = 240 s

        = 240/60 min

        = 4 min
