Question

a train traveling at 60kmph crosses another train traveling in the same direction 50kmph in 30sec.what is the combined length of both train???​

Answer 1

Answer:

since v=d/t then d=v×t distance is 10×30/3600=250/3=83.33

Answer 2

Answer:

the Combined length of both the train is 250/3 m.

Step-by-step explanation:

Given is,

Speed of T1 = 60kmph

speed of T2 = 50kmph

,Time taken = 30 Sec,

L= lenghth ?

Relative speed = T1-T2

60-50 Km/hr = 10

As we know that relative speed = 10 Km /hr

when we convert hour into second

10×5'/18 m/,s

25/9m/s

Time taken by another train = 30 Sec.

combined length of both trains = total distance coverd by both train.

Let the distance coverd by both rain is = X

Speed = Distance / time

25/9 = X/30

X = 25*30/9

X= 250/3 m

So the Combined length of both the train is 250/3 m.
