Question

A 125 metre long train travels at 90km\h. How much time would it take to cross a 175 m long bridge ​

Answer 1

Step-by-step explanation:

Total distance to travel = Lenght of train+Lenght of bridge = 125 + 175 = 300 m

Speed of the train = 90km/hr = 90×5/18 m/s = 25 m/s

Therefore, Time taken = 300/25 = 12 sec.

Answer 2

Answer:

12

Step-by-step explanation:

-> 125+175=300

let's convert 90km/hr into m/s that is 25m/s

then write 300/25 cut digits with 5 and answer will be 12 sec
