Question

a train 80 metres long travelling at 30 metre per second overtakes another train hundred metres long travelling at 20 metre per second calculate the time taken
by the first train to overtake the second train​

Answer 1

Answer:

The time taken by the fist train to overtake the second one is 1.2 seconds.

Step-by-step explanation:

As,

First train's speed(S¹)= 80×20 m/s = 2400m/s.

Second train's speed(S²)= 100×20m/s = 2000m/s.

S¹>S²

Therefore, 2400/2000 = 1.2 Seconds. [Answer]
