Question

. A train of 100 m long crosses a platform of 150 m length in 12.5 sec. Find the speed of
the train.
​

Answer 1

Answer:

20 m/s

Step-by-step explanation:

Length of train = 100 m

Length of platform = 150 m

Total distance = (100+150) m = 250 m

Total time taken = 12.5 seconds

Speed = Distance/Time = 250/12.5 = 20 m/s

Answer 2

Step-by-step explanation:

TOTAL LENGTH = 100+150 = 250 m

TOTAL LENGTH = 250 m

TIME = 12.5s

So, SPEED = DISTANCE / TIME

= 250*10/125 {10 in numerator because 12.5 so point removing so multiply with 100}

= 20 m/s

OR

IF ANSWER IS IN KM / HR SO 20*3.6 = 72 KM/ HR

ANSWER IS 20 m/s or 72 km/ hr
