Question

75. A train of length 120 m, travelling at 30 m/s takes
30 s to overtake another train of length 240 m. If
both the trains are travelling in the same direction,
then find the speed of the longer train.

Answer 1

Answer:

Step-by-step explanation:

So relative speed =30-x (xb be the speed of the other train)

Total distance to cover =360m

So s=d/t

30-x=360/30

30-x=12

X=18m/sec

Please state the answer as brainliest if you understood ...

Answer 2

Answer: 18m/sec

Step-by-step explanation:

So relative speed =30-x (xb be the speed of the other train)

Total distance to cover =360m

So s=d/t

30-x=360/30

30-x=12

X=18m/sec
