Question

A 210 m long took 12 seconds to pass 90m long tunnel find the trains speed
✍✍✍✍

Answer 1

Answer:

Step-by-step explanation:

Given:-

Length of train = 210 m.

Length of tunnel = 90 m.

Solution:-

Therefore, total distance = 210 + 90 = 300 m.

Time taken = 12 s.

Therefore, v = s/t

                   = 300/12.

                   = 25 m/s

Hence, Speed at which the train is crossing the tunnel = 25 m/s.
