60 km/hr *speed= 60 x 5/18 m/sec.

Why in this question, you are saying to find out length of train it must be distance covered by the train?

60 km/hr *speed = 60 x 5/18 m/sec.

1 km = 1000 meters.

1 hr = 3600 seconds.

1 km/hr = 1000/3600 m/s.

Train Cross Stationary object without length.

t = Lt/St.

Lt = length of train.

St = speed of train.

Can I follow this formula for this question as I follow made easy book and for this type of question this formula is used but I'm not getting the answer thru this formula.

Can any 1 help.

Thankyou.

Speed = (60*(5/18)) divide 60&18 by 6, then,
Speed = (10*(5/3)) multiply 10 & 5,
Speed = (50/3).

That's all @Qaazi.
